Pre-AP Pre-Calculus Chapter 1, Section 5 Parametric Relations and Inverses

Inverse Relations & Inverse Functions When you reverse the coordinates of all the ordered pair and solve for the dependent variable, you get an inverse relation. If a function fails the horizontal line test, the inverse function will fail the vertical line test meaning the inverse relation is not a function.

Which of the 4 graphs are a function? Which ones have an inverse that is a function?
