Question

HELP!

Answer 1

its supposed to be f(x+h)-f(x)

Answer 2

over h

Answer 3

\[\frac{f(x+h)-f(x)}{h}\]
\[\frac{3(x+h)^2-2(x+h)-(3x^2-2x)}{h}\]

Answer 4

\[\frac{3(x^2+2xh+h^2)-2x-2h-3x^3+2x}{h}\]
\[\frac{x^2+6xh+3h^2-2x-2h-3x^2+2x}{h}\]
\[\frac{6xh-2h+3h^2}{h}\]
\[\frac{h(6x-2+3h}{h}\]
\[6x-2+3h\]

Answer 5

one question

Answer 6

why not 3x^2?

Answer 7

never mind i see it..thanks!
