1 Horizontal Line Test

2 (Press the Graph to move the red lines)
Horizontal Line Test If a horizontal line intersects a curve more than once, the inverse is not a function. (Press the Graph to move the red lines) Use the horizontal line test to decide which graphs have an inverse that is a function.
