Answer:


f(x) = 500 + 60x

Explanation:

Given


Ope\ ning\ Balance = 500


Deposits = 60 --- monthly

Required

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


f(x) = 500 + 60x

Hence, the function that represents the scenario is


f(x) = 500 + 60x
