I'm kinda new to Open Study, but I'm having trouble on this, I don't understand it. Could someone help me work through this?

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. 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.

it just means the interest on the $200 she has. So 200 is her initial amount and the rest of the new function is the interest function (1.05 is probably the interest added onto the $200 and the x is per year or per month, just depends)
