If F (x) = 3x + 2 and G (x) = x2 + 4, what is F (G (x)) ?

So you in this problem you are supposed to have F (G (x)) what you need to do is plug in g (x) for x in f (x) because it's telling you to find f of g of x so if you plug in g (x) into x in f (x) it would be

F (G (x)) = 3 (x2+4) + 2

and then if you need to solver it just distribute and combine like terms let me know if you have any questions
