SECTION 3.4 EXERCISES Getting Started 1. How do you find the derivative of the product of two funetions that are differentiable at a point? How do you find the derivative of the quotient of two functions that are differentiable at a point? 2. 3. Use the Product Rule to evaluate and simplify ((x + 1)(3x + 2)). dx 4. Use the Product Rule to find f'(1) given that f(x) = x'e . Use the Quotient Rule to evaluate and simplify dx\3x + 2, 6. Use the Quotient Rule to find g'(1) given that g(x) r + 1 7-14. Find the derivative the following ways: a. Using the Product Rule (Exercises 7-10) or the Quotient Rule (Exercises 11-14). Simplify your result. b. By exparading the product first (Exercises 7-10) or by simplifving the quotient first (Exercises I1-4), Verify that your answer agrees with part (a). 7. f(x) = x(x - 1) 8. g(t) = (t + 1)(r - t + 1) 9. f(x) (x - )(3x + 4) 10. h(2) = (z' + 42 + z)(z = 11. f(w) = 4.s 12. g(s) 4s - 8s + 4s 4s 13. y where a is a constant 2ax + a 14. y where a is a constant 5.
