A) This is a function since every x value only goes to one y value.

B) This is a function as every 'x' only maps to one and only one 'y'

C) This is NOT a function because the x value 7 is paired with the y values of 0 and 1. Visually, if you plot these points, the graph would fail the vertical line test.
