2. Use the definition of the derivative to find f' (x) for each function 5 c. f(x) = x + 5 d. f(x) = Vx - 2 6. Determine f'(x) for each of the following functions: fl d. f(x) = Vx + Vx e. f(x) = 7x 2 - 3Vx 8. Determine the derivative using the product rule. c. y = ( 3x2 + 4x - 6) ( 2x2 - 9) d. y = (3 - 2x3) 3 9. Determine the equation of the tangent to y = (5x2 + 9x - 2)( -x2 + 2x + 3) at (1, 48). 10. Determine the point(s) where the tangent to the curve y = 2(x - 1)(5 - x) is horizontal. 11. If y = 5x- - 8x + 4, determine - from first principles
