Id built a tower out of blocks with his nephew. each block was 1 3/4 inches tall,
except the top block, which was only 1 inch tall. they built a 44 3/4 inch tall tower.
how many blocks did they use? use mathematics to justify your answer.

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.
