You have to begin by declaring what g(f(x)) means. It means that wherever you see an x in g(x) you put in f(x).
It will look like this to start with
g(f(x)) = (f(x) + 5) / (f(x)
Now substitute into this for g(-3)
g(x^2 + 5) = (x^2 + 5 + 5)/(x^2 + 5) It's time to use some numbers.
g(- 3) = ((-3)^2 + 10)/( (-3)^2 +5)
g(-3) = ( 9 + 10 ) / ( 9 + 5)
g(-3) = (19)/14 <<<<<< answer.
C <<<< answer.
The answer is C. Have a nice day.

Answer:
x=1.3288 or -1.1288
Step-by-step explanation:
Given 
Subtract 4x from both sides

Since we can factor out 2 from whole equation, let's factor out 2.

Divide with 2 on both sides

We got the quadratic equation, we can solve for x using quadratic formula.
