A. For each of the following functions, find the indicated derivative using the definition. f(x) -L ' 2. 3. 4. = 5x + 12 = 2 sinx; f B. Solve the following problems. Write your solutions and final answers on a separate sheet. Find the equations of the tangent and normal lines to the curve y = x2 + 2x + 3 at x = I. (Note: A normal line is a line perpendicular to the tangent 2. 3. 4. line at the point of tangency.) Find the equation of the tangent line to the curve y 2x 3 that is parallel to the line x + y 1. Find the equation of the tangent line to the curve y x2 3x + 4 that is perpendicular to the line x y 1. Suppose the function is defined by y f(x) x2 x a. Find the average rate of change of y with respect to x over the interval 11, 31. b. Find the instantaneous rate of change of y with respect to x at the point
