Please need answers for 3 & 4 thank you!

3. Compute the exact value of the following definite integral, using the evaluation theorem portion of the F.T.C. (6 points): [(8x3 + 3x2 - e')dx 4. Let f (x) - 6x -11x+7 x2 be a given function: a) Simplify the given function algebraically; then find F(x), the most general antiderivative (6 points). b) Find the specific antiderivative satisfying F(1) - 6, using the result obtained in the previous part (3 points)
