Graphing polynomial functions

Given f(x)= 4x^2=9x+2 and g(x)=3x-2, find and simplify the following:
I have a few other problems i need help with too so if you want to lend me a hand let me know.
We will be happy to critique your thinking.
the standard definition of
(f+g)(x) = f(x) + g(x)
so for your functions
(f+g)(x) = (4x^2+9x+2) + (3x-2)
simplify this and then
follow the same technique for the other two questions, and let me know what you got
