Answer:
-8x^2 - 20
Step-by-step explanation:
(f o g) means (f(g(x)), so let's find that out first
(f(g(x)) means we use the expression from g(x) and insert it into f as x in f(x)
f(x) = 2x-1
(f(g(x)) = 2(x^2 + 3) -1
(f(g(x)) = 2x^2 + 6 - 1 = 2x^2 + 5
now we need to multiple (f o g) by -4
(2x^2 + 5) * (- 4)
-8x^2 - 20
