The table below is for the relation $y=2+x-x^2$

x	-2	-1.5	-1	-0.5	0	0.5	1	1.5	2	2.5	3
y	-4	-1.75	0	1.25	2	2.25	2	1.25	0	-1.75	-4

(a) Using a scale of 2cm to 1 unit on each axis, draw the graph of the relation in the interval $-2\le x\le 3$.
(b) From your graph, find the greatest value of y and the value of x for which this occurs.
(c) Using the same scale and axes, draw the graph of $y=1-x$
(d) Use your graphs to solve the equation $1+2x-x^2=0$
