How do you describe a graph in math?

What is a graph? In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things.

How do you describe a function on a graph?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

What words describe a graph?

• UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
• DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
• UP & DOWN: fluctuate / undulated / dip /
• SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.

How do you describe the graph of an equation?

Defining the Graph of a Function. The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation.

What are the 5 characteristics of a graph?

• Domain, Range, Max, Min, Zero,
• Y-Intercept, Interval of Increase,
• and Interval of Decrease.

How do you find the features of a graph?

Video quote: Range would be the y-value is included in your graph. X-intercept so this is the point where a graph goes through the x-axis. So there can be more than one x-intercept.


What are the seven qualities of a good graph?

Terms in this set (7)

• title. The Effects of (IV) on (DV)
• labelled x and y axis with units. 1cm, 2cm, 3cm.
• origin. (0,0)
• even scaling. 2,4,6,8.
• key. top right corner.
• colors. only when there is more than one line or bar.
• room to extrapolate and interpolate. extrapolate = predict the future.




What does a good graph look like?

Use simplicity in design of the graph



A graph with a simple design strives for a clean, uncluttered look. Simplicity in design does not mean simplicity in data however; well-designed graphs can represent rich data. Avoid distortions, shading, perspective, volume, unnecessary colour, decoration or pictograms, and 3D.

How do you explain a graph to a child?

Video quote: And each bar represents a different color the top of each bar touches a line that represents the number of students that like that color. So 15 students like red 20 students like blue.


Which of the following is a characteristic of a good graph?

Data points should be represented clearly, with easy to distinguish symbols. 9. If you are plotting more than one set of data on the same graph, include a key or legend. Use can use different colors, symbols or types of lines (solid, dashed) to identify different conditions or subjects.

How do you make a nice graph?

TL;DR




1. Pick the right graph. Use the right tool for the job.
2. Sort your data; don’t leave it for Excel to decide where your data will appear.
3. Adjust your axis. Keep your number formats and category titles clean.
4. Check your margins. …
5. Remove unnecessary styling. …
6. Pick your colors. …
7. Format your legend. …
8. Choose your title.




What are the characteristics of a line graph?

A line graph is a graphical display of information that changes continuously over time. Within a line graph, there are various data points connected together by a straight line that reveals a continuous change in the values represented by the data points.

How do you make an effective graph?

Do’s:

1. Use appropriate charts, including horizontal bar graphs.
2. Use the full axis.
3. Keep it simple, especially with animations, and make sure with a squint test.
4. Use color to contrast and highlight data.
5. Ask others for opinions.




How do you make a simple graph?

Video quote: You select the insert tab. And then you go and you pick on the type of chart that you would like I think I would like to have a line chart. And so let's click that to start with.






How do you read a graph?

The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis.

1. The x-axis may contain categories or numbers. You read it from the bottom left of the graph.
2. The y-axis usually contains numbers, again starting from the bottom left of the graph.




Why do we use graphs?

Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space.

What should you include in a graph?

Essential Elements of Good Graphs:




1. A title which describes the experiment. …
2. The graph should fill the space allotted for the graph. …
3. Each axis should be labeled with the quantity being measured and the units of measurement. …
4. Each data point should be plotted in the proper position. …
5. A line of best fit.

What is the use of graph explain with an example?

The points on the graph often represent the relationship between two or more things. Here, for instance, we can represent the data given below, the type and number of school supplies used by students in a class, on a graph.

What are graphs in discrete mathematics?

In discrete mathematics, a graph is a collection of points, called vertices, and lines between those points, called edges. There are many different types of graphs, such as connected and disconnected graphs, bipartite graphs, weighted graphs, directed and undirected graphs, and simple graphs.

What is a graph simple definition?

1 : a diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables. 2 : the collection of all points whose coordinates satisfy a given relation (such as a function)

What is graph in data structure?

What Are Graphs in Data Structure? A graph is a non-linear kind of data structure made up of nodes or vertices and edges. The edges connect any two nodes in the graph, and the nodes are also known as vertices.

What is a graph and how do you represent a graph?

In graph theory, a graph representation is a technique to store graph into the memory of computer. To represent a graph, we just need the set of vertices, and for each vertex the neighbors of the vertex (vertices which is directly connected to it by an edge).





What is graph in data structures and algorithm?

A Graph is a non-linear data structure consisting of nodes and edges. The nodes are sometimes also referred to as vertices and the edges are lines or arcs that connect any two nodes in the graph.

How do you represent a graph in memory?

There are three ways to store a graph in memory:

1. Nodes as objects and edges as pointers.
2. A matrix containing all edge weights between numbered node x and node y.
3. A list of edges between numbered nodes.
