Question

m(n) = 3n³ - 4n
evaluate m(-1)
type answer here.

Explanation:

Step1: Substitute \( n = -1 \) into \( m(n) \)

\( m(-1) = 3(-1)^3 - 4(-1) \)

Step2: Calculate each term

First, calculate \( (-1)^3 = -1 \), so \( 3(-1)^3 = 3\times(-1) = -3 \). Then, \( -4(-1) = 4 \).

Step3: Combine the terms

\( m(-1) = -3 + 4 \)

Step4: Simplify the expression

\( -3 + 4 = 1 \)
