Answer:

f(x)=120+15x

Step-by-step explanation:

Given : Emerson has $120

             Each week, he saves an additional $15.

To Find: Write a function f(x) that models the total amount of money Emerson has after x weeks.

Solution:

He saves in 1 week = $15

He saves in x weeks = $15x

He already has $120

So, total amount of money = 120+12x

So, Function: f(x)=120+15x

Hence  a function f(x) that models the total amount of money Emerson has after x weeks is f(x)=120+15x .

2b^2. This is because you have a positive a^2 and a negative so they cross it one another so it just leaves the b’s.
