What the composite function in the question is actually trying to explain is;


  • (gof)(x)=g(f(5))

First of all, in the function
F(x), we will find a result by writing
5 where we see the letter
x.


  • F(5)=5^2-6(5)+2=-3

We will write this result in the
G(x) function where we see the letter
x and we will get the result.


  • G(-3)=-2(-3)=6
