Starting now, you don't have to use the Definition of the Derivative via Limit -- use any technique you like to find derivatives, including having a lucky guess. Pr 8. Find the equation of the Tangent Line to the curve y = x3 - x at x=2. Show your work. Pr 9. Find the derivative: (3 x 4 - 2 x2 + 5) ' Pr 10. Consider function f (x) = x3 - 12 x a) Find f'(x). b) Find the second derivative, f"(x). Pr 11. Find d t3 - 5 dt t 2 Hint: Divide through first, then use Derivative of a Power rule. Pr 12. Find an equation for the line that is tangent to the curve y = x - 2x + 1 at the point (0,1) and graph the curve and its tangent line (on a reasonable interval).
