Each year, the junior class at East High School sells discount cards as a fundraiser. Each $20 discount card is valid for a year and provides discounts at many area businesses. This year’s juniors are analyzing the revenue, or earnings, from past years and this year. If n represents the number of cards that students sold last year, match each algebraic expression to what it represents. Drag the tiles to the correct boxes. Not all tiles will be used.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
