Given the binomial z = 2x − 3 find z3 − 5z + 7

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.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
