(a) Copy and complete the following table of values for the relation $y=x^2-2x-5$

x	-3	-2	-1	0	1	2	3	4	5
y			-2		-6	-2	3	10

(b) Draw the graph of the relation $y=x^2-2x-5$; using a scale of 2 cm to 1 unit on the x- axis, and 2 cm to 2 units on the y- axis.
(c) Using the same axes, draw the graph of $y=2x+3$.
(d) Obtain in the form $a{x}^2+bx+c=0$ where a, b and c are integers, the equation which is satisfied by the x- coordinate of the points of intersection of the two graphs.
(e) From your graphs, determine the roots of the equation obtained in (d) above.
