A, B, and C wanted to compute the area under the curve f(x)=x−2+2x−6x3+cos(x) over the interval [2,10]. To do this, each one used a different anti-derivative. B used the antiderivative F(x)=−1x11+x2−2x3+sin(x). A used the antiderivative F(x)=−x−11+x2−2x3+sin(x)+2020. C used the antiderivative F(x)=−2x−3+x2−2x3+sin(x). Who, if anyone, completed this problem correctly? a) All three are correct b) Only B c) Only A and B d) Only C e) Only A f) None of them.
