11. For the rational function f(x) = 3x- - x-2. [10] x2 - 4 a) Determine its x- and y-intercepts. b) Find its vertical asymptotes and determine the behaviour of f(x) on either side of each VA.c) Find its horizontal asymptote and determine the behaviour of f(x), either above or below the HA, as x -> too and x -> -co. 10 -9 -8 -7 -6 -3 -4 -3 -2 -1 1 2 3 4 5 6 7 5 9 10 x d) Use this information to sketch a graph of f(x)
