The range of f is all reals except 0 , so the domain of f−1 is all reals except 0 . We can see from this that for the original function, f , we can get every number for y except 0 .

How do I find the domain and range of a function?

To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

What is the domain and range?

Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
