Best ResponseYou've already chosen the best response.0f(x+(delta)x)  f(x)/(delta)x lim as (delta)x approaches 0..... f(x) = x^2  4x

Best ResponseYou've already chosen the best response.0or if you wanna get really wild: delta x = partitional section of the distances from x to som interval that goes to zero; but h is simpler eh lol

Best ResponseYou've already chosen the best response.0(x+h)^2 4(x+h)(x^2 4x) //h x^2 +h^2 +2xh 4x 4h x^2+4x//h

Best ResponseYou've already chosen the best response.0cancel the terms that cancel and get: h^2 +2xh 4h//h h + 2x 4 when h = 0 is 2x 4

Best ResponseYou've already chosen the best response.0your learning that the longway to get to the derivative just proves the shortcut methods lol

Best ResponseYou've already chosen the best response.0ok so 2x4 is the limit?

Best ResponseYou've already chosen the best response.0and yes, the lim would be 2x4; since the lim as h>0 of f(x) is the definition of a derivative
