Question

What is this?!?!? Need an answer in 24hrs please.

Answer 1

Answer:

X

Step-by-step explanation:

To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.

To help: draw vertical lines through each graph.

In graph W: the line would pass through the top and bottom of the circle - not a function

In graph X: the line passes once through every area - a function

In graph Y: the line passes through the top curve as well as the bottom curve - not a function

In graph Z: the line passes through the curves multiple times - not a function
