Question

Math question.

Answer 1

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.

@AbdullahM

Answer 4

The only way we can combine them to get a useful function is h(x) * s(x), which is the same thing as \(\bf (h\cdot s)(x)\)

That's not the same thing as \(\bf (h\circ s)(x) = h(s(x))\)

Also, I believe you meant to say \(\bf s(x) = (1.04)^{x - 1}\)

Answer 5

yes its ^x-1 sorry

Answer 6

It's ok

Answer 7

so we would multiply the two?

Answer 8

Yes

Answer 9

Answer 10

This new function will allow Tommy to know how much money he has (including interest) after x time in the savings account.
