Question

Graph h(t)=-2(t+5)^2+3, find h(-8)

Answer 1

• Answer:

h(-8) = - 15

• Explanation:

h(t) = - 2(t + 5)² + 3

replace t with - 8

h(-8) = - 2(- 8 + 5)² + 3

h(-8) = - 2(-3)² + 3

h(-8) = -2×9 + 3

h(-8) = - 18 + 3

h(-8) = - 15

Answer 2

h(-8)=-15

Explanation:

Substitute t=-8

h(-8) =-2(-8+5)^2+3

=-2(-3)^2+3

=-2(9)+3

=-18+3

=-15
