Best ResponseYou've already chosen the best response.0but for some reason I'm not getting the right answer for F(1.2)

Best ResponseYou've already chosen the best response.0I found that since F(0)=0, then that must mean C=0. And then I pluged in 1.2 for the t's in the antiderivative and got 4.032 but the webwork says my answer's wrong, so I'm confused
