Functions find the values

Question

Use the functions  f(x)=−4x^2−7x+9 and g(x)=-2-7 to answer the following questions.

f(-3)=____

g(f(-6))=____

Answer 1

f(-3) = -4(-3)^2 - 7(-3) + 9 =-36 +30 = -6

f(-6) = -4(-6)^2 -7(-6) +9 = -4(36) +54 +9= -144+63=-81

g(f(-6)) = g(-81) = 2-7 = -5

UNLESS you really meant to have an x term in g(x)

such as perhaps 2x-7, then

g(-81) = 2(-81)-7 =-162-7 = -169
