step-by-step explanation:

the graph can only show a function if it has 1 y-value (output) for every x-value (input). they have to pass the vertical line test (if the vertical line touches two spots on the graph's line, it is not a function). since the x values on the graph have a positive and negative y-value, if you pass a vertical line through the graph it will touch 2 points. therefore, the graph does not show a function because the graph fails the vertical line test.
