OR TEACHER Use g(x) = _Ax3 B - 8x3 where A # 0, B # 0 to answer the questions below. (a) Find the equation of the vertical asymptote of g(x) . If there is no vertical asymptote, write NONE. (b) If y = _ is the horizontal asymptote of g(x) , find the value of A. A = (c) Find g'(x) . Express your answer as a single simplified fraction. g' ( x ) = (d) Find the critical point(s) of g(x) . If there are no critical points, write NONE. If there is more than one critical point, enter your answers separated by commas. X =
