Question

Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x − 1. After combining the two functions, his new function is g(x) = 350(1.04)x − 1. Using complete sentences, explain what this new function means.
