Victoria has $200 of her birthday gift money saved at home, and the amount is modeled by the function h(x) = 200. She reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.05)x−1. Explain how Victoria can combine the two functions to model the total amount of money she will have in her bank account as interest accrues after she deposits her $200. Justify your reasoning.

@darkknight

darkknight:

This one would be exactly like the 2nd problem you asked! Where are you stuck?

esha1963:

combine the two?

darkknight:

Yeah.

esha1963:

so i would combine s(x) and h(x) and then how can i justify my reasoning?

darkknight:

You would combine both of those because both functions are functions of her savings.

esha1963:

okay thanks!
