Chapter 3.3, Problem 9QR

Find the derivatives of the following functions using the  formula of derivatives

2. Find the derivative of each function: cos (x) 1-x² (b) g(x) = 5³√x - (a) f(x): (c) f(x) = (3x² + x − 12)(7x² − 4x) - (d) s(t) = 2t³ - 8t+4

3. Determine the derivative of the function with respect to x. (Arrange your answer from highest degree to lowest degree) y = (x² + 1)(x³ – x²)
