Question

Use the vertical line test to determine if the graph below represents a function. If it is not a function, tell where the vertical line test fails.

Answer 1

Answer:

see attached

Step-by-step explanation:

The vertical line test for a function passes when, if you draw a vertical line which intersects the graph, the line intersects the graph at ONLY ONE point.

It is quite clear that for all positive values of X, any vertical line will intersect the graph at 2 points, thereby failing the vertical line test for a function.
