Answer 1

Answer:

The answer to your question is:    k(-5) = -115

Step-by-step explanation:

Function       k(n) = n³ - 3n      find k(-5)

                    k(-5) = (-5)³ - 3(-5)             substitution

                    k(-5) = -125 + 15                simplify

                    k(-5) = -115
