Question

Which rationale best describes why the functions are inverses? The functions intersect each other The functions have the same general curve. The functions are reflections over the line y = x One function has an x- intercept and the other has a y-intercept

Answer 1

Answer: It was the third answer. C.

Answer 2

The rationale that best describes why the functions are inverses is (c) the functions are reflections over the line y = x

How to determine the true statement?

Take  for instance, the following function:

y = x + 2

The first step in determining the inverse is to swap x and y.

So, we have:

x = y + 2

The above means that the equation y = x + 2 is reflected across the line y = x

Hence. the rationale that best describes inverse functions is (c) the functions are reflections over the line y = x
