Question

find the difference quotient

find f(x+h)-f(x)/h
h is not equal to 0

f(x)=-2x^2+5x+2

Answer 1

f'(x)=-4x+5 is where the answer is going when h becomes infinitesimally small

Answer 2

ok..thats the answer??

Answer 3

as best as I can describe it. You may need to form the answer like:
(-2(x+h)^2+5(x+h)+2 -2x^2+5x+2 )/h

Answer 4

.. and simplify

Answer 5

ok thank you!!!!!!!!!!!!

Answer 6

Yea, sound like you are on the way to discovering the foundation of derivative Calculus. I wont ruin it for you.
