Suppose u and v are functions of x that are differentiable at x = 0 and that u(0) = 4, u'(0) = 7, 0(0) = 3, v'(0) = 6 Evaluate the following derivatives. (a) %(6v3u) x=0= i (b) inn); = i. (c) %(%)x= = i 1) 5)\" = i 2 For what values of a and b is the line 2x + y = b tangent to the curve y = ax when x = 1 ? The graph of f (x) = 2x3 + 9x2 60x + 9 has two horizontal tangents. What are the values of x where horizontal tangents occur? x= Z Your answer should be a list of values
