8. (1 point) Find the equation of the tangent line to the curve 32 = x x at the point (16, 64). y = 10. (1 point) Find the xcoordinates of the points on the curve y : 2x3 + 6x2 18x 1 where the tangent is horizontal. List these xcoordinates below. If there are multiple values, separate them with commas. x: 13. (1 point) 7-2 if x 1 Find the values of m and b that make f(x) differentiable. m b =14. (1 point) Consider the following equation: 11 _ m) 2 1m f_0 Let f (x) : 3/} If a 75 0, use the above formula to nd f'(a) : Hint: use the formula (.5; b) (a2 + ab + 192) : a3 1:3 Now show that f' (0) does not exist and that f has a vertical tan gent line at (0,0) \f
