Is the absolute value of x an even function?
Space and AstronomyBy definition, a function f(x) is even if f(−x)=f(x) , and it is odd if f(−x)=−f(x) . So in the case of the absolute value function, it is clear that f(−x)=f(x)∀x∈R and hence it is an even function. Is the absolute value of x function even or odd? even function It is an even function.

What is the brightest absolute magnitude?
Space and AstronomyAbsolute magnitudes are how bright a star would appear from some standard distance, arbitrarily set as 10 parsecs or about 32.6 light years. Stars can be as bright as absolute magnitude -8 and as faint as absolute magnitude +16 or fainter. What is the brightest star in terms of absolute magnitude? A more complex definition

What is the meaning of a waning crescent moon?
Space and AstronomyDuring the Waning Crescent Moon phase, the lit-up part of the Moon decreases from 49.9% to 0.1%. The phase lasts from the Third Quarter Moon’s semicircle until it disappears from view at New Moon. Waning means that it’s shrinking and getting smaller, while crescent refers to the curved sickle shape. What does a waning crescent

What changes a translation?
Space and AstronomyWhat changes when doing a translation? In geometry, a translation moves a thing up and down or left and right. Notice how the segment’s direction and length stayed the same as you moved it. Translations only move things from one place to another; they don’t change their size, arrangement, or direction. What changes after a

Are conics functions?
Space and AstronomyConic sections are relations, not functions. An equation (like for example x2+y2=100) can be thought of as a criterion or condition that can be used to check any point to see if it is part of the relation. Is all conic sections are functions? If the plane does pass through the vertex, various degenerate conic

Which of the following is an advantage of reflector telescopes over refractor telescopes?
Space and AstronomyReflecting telescopes have many advantages over refracting telescopes. Mirrors don’t cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be used to attach to the mount. Why are reflector telescopes better than refractor telescopes? Refractor telescopes use specialized lenses

Is the edge of a half plane another half plane?
Space and AstronomyAnswers. Half-Plane. A half-plane is a planar region consisting of all points on one side of an infinite straight line, and no points on the other side. If the points on the line are included, then it is called an closed half-plane. Can a plane be divided into two half planes? Each line plotted on
