For f(x) 3x - x^2 Find: f(x+h) f(x) ---------- h
Is there a picture? (I don't understand the question.)
i think it should be: [f(x+h)-f(x)]/h
then f(x+h)=3(x+h)-(x+h)^2 and f(x)=3x-x^2 and you make the substitution, crank through the algebra, cancel the h's in the appropriate places, and you are done
Oh ok i was just confused over the h part. The substitution i got hands down.
