Answer:

see below

Step-by-step explanation:

f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5

f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559

g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72

h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337

Explanation:

f(-8) = 5(-8)^3 + 1
f(-8) = 5(-512) + 1
f(-8) = -2560 + 1
f(-8) = -2559

g(-6) = -2(-6)^2
g(-6) = -2(36)
g(-6) = -72

h(9) = -4(9)^2 -2(9) + 5
h(9) = -4(81) - 18 + 5
h(9) = -324 - 13
h(9) = -337
