Christina has $103 earned from babysitting saved at home, and the amount is modeled by the function h(x) = 103. She reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.03)x − 1. After combining the two functions, the new function is g(x) = 103(1.03)x − 1. Using complete sentences, explain what this new function means.
Accepted Solution

s(x)=1.03x−1
then you should use parens around the (x-1)
It means that her deposit is getting 3% larger each period set by the bank (i.e. month, year...).
