Answer:

1

Step-by-step explanation:

First we can solve for [tex]g(x) = 2x[/tex] where [tex]x = 4[/tex] so we get: [tex]g(4) = 8[/tex].

Then we put that into the [tex]f(x) = x - 7[/tex]. So we now have: [tex]f(8) = 8 - 7 = 1[/tex]

Answer:

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.
