I would greatly appreciate it! Question Consider the graph of the function f(x)=x^2-x-12. (a) Find the equation of the secant line joining the points (-2, -6) and (4, 0). (b) Use the Mean Value Theorem to determine a point c in the interval (-2, 4) such that the tangent line at c is parallel to the secant line. (c) Find the equation of the tangent line through c. Answers a) y=x-4 b)f'(c)=1 c)y=x-13 Thank you!    03-09-2013   #2
