1. (a) Find all horizontal and vertical asymptotes of the following function. f (x ) = x2 - 8.x - 9 6x2 + x -5 (b) Find all slant/ oblique and vertical asymptotes of the following function. f(a) = x3 - 2x + 1 x2 - 8.x + 12 2. For the following rational function (a) state the domain of the function, (b) identify x and y intercepts, (c) find any horizontal and vertical asympototes, (d) by plotting additional points, sketch the graph of the rational function. f(x) = 5 + 3x 2 - x 3. Solve the following inequalities by considering "key points". (a) x2 - 5x -14 > 0, (b) x2 + 9.x+15-17
