Question

Which graph represents a function??

Answer 1

Bottom Right

Explanation:

A function has only one y value for every x value. The upper left graph has many y values for the x value of 1, the bottom left graph has two y values for each x value and so does the upper right graph. the Bottom right graph is the only option with one y value for every x value.

Answer 2

To be a function a graph must pass the vertical line test and the only one that does this is the bottom right one.
