Q5) (a) On the same set of axes plot the graphs, in intervals of 1, of y = x² + 2x - 3 in the range - 4 ≤ x ≤ 3 and y = 4 - x² in the range - 3 ≤ x ≤ 3 (12)

Suggested scales: horizontal axis 2cm = 1

vertical axis 1cm = 1

(b) Using the graphs drawn in Q5(a), solve the system of quadratic equations:

y = 4 - x²

y = x² + 2x – 3 (4)
