Comment 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.
