Explanation:

f(g(x)) means g(x) is embedded in f(x) as the argument or input value for f(x).

therefore,

f(g)x)) = 4(x² - 1) - 7 = 4x² - 4 - 7 = 4x² - 11

c. is the right answer

g(f(x)) is now the other way around. now f(x) is the only value for g(x) :

g(f(x)) = (4x - 7)² - 1 = 16x² - 56x + 49 - 1 = 16x² - 56x + 48

a. is the right answer
