For each of the given functions, f(r), find an antiderivative, F(r), that satisfies the given initial condition. a) f(x) = 1; F(1) = 1. b) f(x) = 2x2 + r; F(1) = 3/2. 3. Find the indicated integrals. A substitution will do the job in each case. Some algebraic simplification of the integrand may be needed first.
