SOLUTION: f(x) = 2-x^2 find (f(3+h)-f(3))/h f(3)=2-9=-7 f(3+h)=2-(3+h)^2=2-(h^2+6h+9)=-7-h^2-6h so (f(3+h)-f(3)) = -7-h^2-6h - -7 = -h^2-6h then (f(3+h)-f(3))/h = -h-6 can I make t

Question 233372: f(x) = 2-x^2 find (f(3+h)-f(3))/h
f(3)=2-9=-7
f(3+h)=2-(3+h)^2=2-(h^2+6h+9)=-7-h^2-6h
so (f(3+h)-f(3)) = -7-h^2-6h - -7 = -h^2-6h
then (f(3+h)-f(3))/h = -h-6 can I make that h+6 or not?? Did I do this correctly?

------------------
You did it correctly.

No you cannot change it to h+6.
You could simplify it to -(h+6)
