Find the derivative of the function. - 3x 3x -3x 2 - 5 f(u) du = f(u) du + f(u) du Hint: 9(x) = du 42 + 5 JZx /2x g'(x) =\fEXAMPLE 5 Evaluate the integral below. ID :9de 1 SOLUTION The function x} = e" is continuous everywhere and we know that an antideriyatiye is F[x) = 5*", so Part 2 of the Fundamental Theorem giyes ID 1 Notice that the Fundamental Theorem of Calculus says we can use any antideriyatiye F of f. So we may as well use the simplest one, namely F{x} = e\
