Which statement could be used to explain why the function h (x) = x has an inverse relation that is also a function?

TO

The graph of h (x) passes the vertical line test.

The

The graph of the inverse of h (x) is a vertical line.

The graph of the inverse of h (x) passes the horizontal line test

The graph of h (x) passes the horizontal line test

The graph of h (x) passes the horizontal line test

Step-by-step explanation:

A function must pass the vertical line test. (Otherwise, it is not a function.) In order for the inverse of a function to be a function, it, too, must pass the vertical line test. Equivalently, the original function must pass the horizontal line test if its inverse relation is to be a function.
