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.

yes i will put it into complete sentences

ganeshie8 · Answer

The question is a bit ambigious, but $x$ should  represent the "time in years"  I guess

ganeshie8 · Answer

He is investing 350, look at the function g(x) 

$$\LARGE g(x) = 350* (1.04^x − 1) $$

ganeshie8 · Answer

Is the expression exactly like that in your assignment ?

Particularly that "x" -  is it in the exponent ?
