Victoria has $200 of her birthday gift money saved at home, and the amount is modeled by the function h(x) = 200. She reads abou
t a bank that has savings accounts that accrue interest according to the function s(x) = (1.05)x − 1. After combining the two functions, the new function is g(x) = 200(1.05)x − 1. Using complete sentences, explain what this new function means.
The total amount of interest that Victoria will receive (g(x)) is equal to the original amount (200$) multiplied by the rate of interest (1.05) multiplied by the time that Victoria keeps her money in the bank (x) minus one.
