Question

H(t) = t² – 2t

Evaluate h (x + 2)


Need help I’m reviewing for a final (will leave good review)

Answer 1

h(x + 2) = x² + 2x

Explanation:

The base function is :

⇒ h(t) = t² -- 2t

⇒ h(t) = t (t - 2)

Substitute x + 2 in place of t :

⇒ h(x + 2) = (x + 2) (x + 2 - 2)

⇒ h(x + 2) = (x + 2)(x)

⇒ h(x + 2) = x² + 2x

Answer 2

`h(t) = t^2 -2t\\\\h(x+2) = (x+2)^2 - 2(x+2)\\\\~~~~~~~~~~~~=x^2 +4x + 4 -2x -4\\\\~~~~~~~~~~~~=x^2 +2x`
