(a) Complete the table below for the equation y = x³ – 3x² – 9x + 2.

b) On the grid provided draw the graph of y = x³ – 3x² – 9x + 2 for -3 < x < 5.
Use the scale: 1cm rep 1 unit on x – axis
1cm rep 5 units on y – axis
c) i) Use your graph to solve the equation
x³ – 3x² – 9x + 2 = 0
ii) By drawing a suitable straight line on the graph solve the equation.
x³ – 3x² – 9x + 2 = -2x – 4
