Which of the following statements is true? all the answers are correct. if a function has an inverse function, then the original function will pass the horizontal line test. a function will always pass the vertical line test. if the function has an inverse function, then the inverse function will pass the vertical line test.

All the answers are correct

Step-by-step explanation:

Any relation that is a function will pass the vertical line test, regardless of any other characteristic it may have (such as being the inverse of some other function).

The inverse of a function is that function reflected across the line y=x. If the inverse passes the vertical line test (is a function), then the original must pass the horizontal line test. The reflection of a vertical line is a horizontal line and vice versa.
