Question

Tommy has some money at home from his graduation modeled by the function h(x) = 350. He read about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x − 1. Tommy is thinking about putting his money into the savings account to gain interest. Using complete sentences, explain to Tommy how he can combine his functions to create a new function, and explain what this new function means.

Answer 1

You should try doing this yourself, think about it, to combine those functions, he will have to actually give 350 to the bank, which would then be given interest over according to the function s(x), so how would you put h(x) into s(x) to get the answer? Try it :)

Answer 2

idk add it together?

Answer 4

Nono, you plug them in together, as in, s(h(x)... Therefore, you'd replace the variable in s(x) with the constant in h(x). This is ofcourse assuming there is no variable defining time. Therefore it'd be (1.04)*350 - 1.
