b) On the grid provided draw the graph of y = x3 − 3x2 − 5x + 7 for −3 ≤ 𝑥 ≥ 5. (Use 2cm to represent 1 unit on the x- axis and 1 cm to represent 5 units on the y-axis).
c) Use the graph to solve the equation x3 − 3x2 − 5x + 7 = 0
d) By drawing a suitable line, use the graph in (b) to solve the equation x3 − 3x2 − 10x + 17 = 0.
