Best ResponseYou've already chosen the best response.1Find the antiderivative 2 times.. So first \[f \prime (x) = 12x^3 + 12x^2 + C\]

Best ResponseYou've already chosen the best response.1We need to find what Cx and what D is.. Im trying to think how to do that

Best ResponseYou've already chosen the best response.1Right which would make Cx = 1

Best ResponseYou've already chosen the best response.1I ment it would make C = 1.. not Cx

Best ResponseYou've already chosen the best response.0if you do that you graph does not have a horizontal tangent line at (0,1) So c=1
