Question

K(t) = t² + 2t; Find k(−8)​

Answer 1

48

Explanation:

So -8^2 + 2(-8): 64-16=48

Answer 2

k(-8) = 48

Explanation:

Hello!

You can find k(-8) by substituting -8 for t in the equation.

Evaluate k(-8)

• k(t) = t² + 2t
• k(-8) = (-8)² + 2(-8)
• k(-8) = 64 - 16
• k(-8) = 48

k(-8) is 48.
