3. Find the derivative of the following functions: (5 points each) a. f(x) = 4x7 - 8x2 b. f(x) = 2x2/x5 c. f(x) = (3x2 + 8) (7x5 -3) [Use the product rule] d. f(x) =(2x2 + 8) / (3x5-3) [Use the quotient rule] e. f(x) = (2x7 + 7x)4 [Use the chain rule] f. f(x) = sin (x) g. f(x) = In x h. f(x ) = ex i. f(x) = sin (x3) j. f(x) = In 4x k. f(x) = e 3x
