(i) Show that - y ++ 3y- 2 = (r-y+2)(r +y-1) and hence, or otherwise, indicate by means of a sketch the region of the r-y plane for which ² - y? +* + 3y > 2. (ii) Sketch also the region of the r-y plane for which 2 - 4y? +3r – 2y <-2. (ii) Give the coordinates of a point for which both inequalities are satisfied or explain why no such point exists.
