Q5. (a) Draw the graph of y₁= x³ in the range x = -2 to x = 2 in intervals of 0.5. (8)

Suggested scales:      horizontal axis 2 cm = 0.5

vertical axis 2 cm = 2

(b) Using the same graph paper and the same axes as in Q5(a), draw the graph of y₂ = 5 - 2x in the range x = -2 to x = 2 in intervals of 0.5. (4)

(c) Using the graphs drawn in Q5(a) and Q5(b), determine the solution to the following equation: (4)

x³ + 2x - 5 = 0
