Given f(x)= 4x^2=9x+2 and g(x)=3x-2, find and simplify the following:

(f+g)(x)

(fg)(x)

(f-g)(3)

I have a few other problems i need help with too so if you want to lend me a hand let me know.

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
