x
On separate axes sketch the graphs of
(a) y = -f(x) (3)
(b) y = f(-x) (3)
5. Sketch the graph of the curve given by the equation y = x 2 - 3x and, on the same
axes, the graph of the equation y = x(x 2 - x - 6) taking suitable values of x.
Find the coordinates of the points of intersection of the two curves. (6)
