2x27x+8_ 12. For the rational function g (x) = 2 x [10] a) Find its critical points. b) Find its vertical asymptote and determine the behaviour of g(x) on either side of the VA. c) Find its oblique asymptote and determine the behaviour of g(x) either above or below theOAas x)+oo and x)00. d) Use this information to sketch a graph of 30)- V
