a. For a graph to be a function, it must pass the vertical line test. The vertical line test is a test you do by drawing vertical lines through the graph and checking to see if, at any point, the line cuts the graph more than once, if it does cut the graph more than once, then the graph isn't a function Eg.|dw:1443505429946:dw|
