what are all values of xfor which the function f defined by f (x) = 3 - 2x. If g is a function with derivative given by g' (x) = f(x) f'(x) (x - 3), on what intervals is g Increasing? a. (-oo, and [3, co) b. -co, only C. . 3 only d. , 0. only e. [3, 00) only 10) Consider the function f defined by f(x) = ex cos x with domain [0,2x]. Find the intervals on which f is increasing. 11) The function y = g(x) is differentiable and increasing for all real numbers. On what intervals is the function y = g(x3 - 6x2) increasing? a. (-00, 0] and [4, co) only b. [0,4] only c. [2, co) only d. [6, 00) only e. ( -00 , 00 ) 12) Particle X moves along the positive x-axis so that its position at time t 2 0 is given by x(t) = 5t3 - 9t2 + 7. At what time t 2 0 is particle X farthest to the left? Justify your
