F (x) = 2+x, (g.

f) (x) = 2x+4+8

g (x) = 2x+8

Step-by-step explanation:

We are given that f (x) = 2+x

And

gof (x) = 2x+4+8

It seems that some part of this problem is missing. We are presuming that we are required to find g (x)

Now

gof (x) = 2x+4+8

=2 (x+2) + 8

=2f (x) + 8

Hence

gof (x) = 2f (x) + 8

In order to find g (x) we replace f (x) with x

Thus g (x) = 2x+8
