(a) Copy and complete the table of values for the equation \(y = 2x^{2} - 7x - 9\) for \(-3 \leq x \leq 6\).

x	-3	-2	-1	0	1	2	3	4	5	6
y		13		-9	-14		-12		6

(b) Using scales of 2cm to 1 unit on the x- axis and 2cm to 4 units on the y- axis, draw the graphs of \(y = 2x^{2} - 7x - 9\) for \(-3 \leq x \leq 6\).

(c) Use the graph to estimate the :

(i) roots of the equation \(2x^{2} - 7x = 26\);

(ii) coordinates of the minimum point of y;

(iii) range of values for which \(2x^{2} - 7x < 9\).
