Steve’s savings account has a balance of $1287. after 4 years, what will the amount of interest be at 6% compounded semiannually?

A = P (1 + r/n)^nt

A =1287 ( 1 + 0.06/2)^8

A= 1287 ( 1 + 0.03)^8

A= 1287 ( 1.03)^8

A = 1630.33

1630.33 - 1287 = 343.33

interest will be $343.33

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.
