Question

F(x)=2+x ,(g.
f)(x)=2x+4+8

Answer 1

g(x)=2x+8

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
