Question

Using Functions Notation

Given the following functions:
f(n) = 2n + 3, g(n) = n³ + 4
Find the following:
f(4) - f(2)

Answer 1

4

Explanation:

***Your question is asking for f(4) - f(2)***
If so, this is the answer:

`f(4) = 2\cdot4 + 3 = 11\\\\f(2) = 2\cdot 2 + 3 = 7\\\\f(4) - f(2) = 11 - 7 = 4`
