Question

For f(x) 3x - x^2

Find:
f(x+h) f(x)
----------
h

Answer 1

Is there a picture? (I don't understand the question.)

Answer 2

i think it should be: [f(x+h)-f(x)]/h

Answer 3

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

Answer 4

Oh ok i was just confused over the h part.

The substitution i got hands down.

Answer 5

okeedokee.
