Given h (f) = -2 (t+5) ^2 + 4, find h (-8)

h (-8) = 22

Step-by-step explanation:

Plug - 8 in for t and simplify ...

h (-8) = 2 (-8 + 5) ² + 4

h (-8) = 2 (-3) ² + 4

h (-8) = 2 (9) + 4

h (-8) = 18 + 4

h (-8) = 22

Step-by-step explanation:

Given h (f) = -2 (t+5) ^2 + 4

There is an intermediate step which is

h (f) = - 2 (f + 5) ^2 + 4

h (-8) = - 2 (-8 + 5) ^2 + 4

h (-8) = - 2 (-3) ^2 + 4

h (-8) = - 2 (9) + 4

h (-8) = - 18 + 4

h (-8) = - 14
