4. Sketch the following curves: NOTE: For each curve you must address the following then do your sketch: Domain, x-intercept(s), y-intercept(s), Stationary point(s) (Find and classify if any exist), Asymptote(s) (if any exist) (a) y = 2x+3x+1 [4 mks] (b) y=2(x+1) [5 mks] (c) y=x-6x+11x - 6 [5 mks] [Hint: This can be factorised as y = (x-1)(x-2)(x-3)] (d) y = 2x-6 2-5 [7 mks] (e) y = x2-x+1 2-2 [7 mks]
