Question

K(a)=2a^2-a; find k(-3)

Answer 1

Answer:

The answer to your question is:     k (-3) = 21

Step-by-step explanation:

Function

                k(a) = 2a² - a       find k(-3)

                k(-3) = 2(-3)² - (-3)

                k(-3) = 2(9) + 3

                k(-3) = 18 + 3

                k (-3) = 21
