Hello, I'm looking for f given f'' and two conditions. [PLAIN]http://img375.imageshack.us/img375/2572/antider.jpg [Broken] Going from f'' to f', I get f'(x) = 5x^4 + 4x^3 + 4x + C But with the two conditions, I feel that I cannot progress from here. I feel that one of those conditions should be f'. Any help is appreciated. Thanks.
