1. Let F(x) be the antiderivative of f(x). If I gave you a graph of f(x), describe how you would determine which x-values are critical values of F(x). 2. Use the Second Fundamental Theorem of Calculus to find the following integrals. Show your work. You do not have to simplify your answers. In fact, I'd rather you didn't! (a) x' + 1 dx = ( b ) e -1 ( c ) sin t dt =
