If f(x)=2x-8 and g(x)=x^4, what is (g°f)(5)? i need the correct answer

(g°f)(5) is equal to 16.

In order to find a composite function's value like this one, you first need to evaluate the first function. Since f is on the right side, we put the value in parenthesis in for x in that equation first.

f(x) = 2x - 8

f(5) = 2(5) - 8

f(5) = 10 - 8

f(5) = 2

Now once you have an answer in the first part of a composite function, we stick the answer we got in for the second part. Since g is on the left side, we put our answer (2) into g.

g(x) = x^4

g(2) = 2^4

g(2) = 16

Therefore, (g°f)(5) = 16
