Help me please????????????????????????

Answer 1

f(x)=500+60x

So, B.

Explanation:

Opening balance =500

Deposits= 60__ monthly

Write as a function

Represent the number of months with x and the balance at any month with f(x)

f(x) is calculated as thus:

Opening Balance + Deposits * Number of Months

So, we have:

f(x)=500+60*x

So, f(x) = 500+60x
