Question

Perform the indicated operation.
g(n)=n^3+n
f(n) = 3n + 5
Find (g - f)(n)

Answer 1

Ummm that’s hard lol sorry

Answer 2

Explanation:

`g(n) = {n}^(3) + n \\ \\ f(n) = 3n + 5 \\ \\ (g - f)(n) = g(n) - f(n) \\ =( {n}^(3) + n) - (3n + 5) \\ = {n}^(3) + n - 3n - 5 \\ \purple{ \boxed{ \bold{ \therefore (g - f)(n) = {n}^(3) - 2n - 5 }}}`
