(HELP PLEASE) For f(x)=-2x^2+3x+1, find f(2+h)-f(2)/h. Simplify completely. (do I plug in F(x) into the fraction or is it the other way around?)

OpenStudy (shamim):

f(x)=-2x^2+3x+1 f(2)=?

OpenStudy (coconutjj):

is f(2)/h or [f(2+h) - f(2)]/h

OpenStudy (usukidoll):

definition of the derivative

OpenStudy (usukidoll):

yeah you're supposed to plug it in to the fraction... you know you have done it correctly if all of the h's cancel
