Question

if f(x) = x-x^2 find and simplify f(x+h)-f(x) / h where h does not equal 0

Answer 1

f(x+h)=(x+h)-(x+h)^2
x+h -x^2-2xh-h^2
x+h-x^2-2xh-h^2-(x-x^2)/h

Answer 2

doesn't look any simpler! Maybe there is an error...

Answer 3

You can simplify the numerator and then an h from both top and bottom will cancel
