Given f(x) = x − 7 and g(x) = x2 . Find f(g(4)).

Step-by-step explanation:

f(x) = x − 7

g(x) = x²

To find f(g(4)) we must first find f(g(x)).

To find f(g(x)) substitute g(x) into f(x) that's for every x in f (x) replace it with g(x)

That's

f(g(x)) = x² - 7

To find f(g(4)) substitute the value of x that's 4 into f(g(x)) that's replace every x in f(g(x)) by 4

That's

f(g(4)) = 4² - 7

= 16 - 7

We have the final answer as
