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

1

Step-by-step explanation:

First we can solve for where so we get: .

Then we put that into the . So we now have:

9

Step-by-step explanation:

Ok so if g(x) is 2x, then I'm wrong, but if it's x squared then look below:

Since there is a 4 instead of a x in g(x), we would substitute x=4 into g(x) so:

g(x) = x^2

g(4) = 4^2

g(4) = 16

Now we would substitute x=16 into f(x):

f(x) = x - 7

f(16) = 16 - 7

f(16) = 9

So f(g(4)) is 9.
