(a) Copy and complete the table of values for the relation:
y = -3x2 + 12x for -2 < x < 6.

(b) Using a scale of 2cm to 1 unit on the x-axis and 2cm to 5units on the
y-axis, draw the graph of y = -3x2 + 12x.
(c) On the same axes, draw the line y = 5x – 10.
(d) On your graph, shade the region for which 7x + 10 > 3x2.
