The following is an incomplete table for the relation $y=2x^2-5x+1$

x	-3	-2	-1	0	1	2	3	4	5
y			8	1		-1			26

(a) Copy and complete the table.
(b) Using a scale of 2cm to 1 unit on the x- axis and 2cm to 10 units on the y- axis, draw the graph of the relation $y=2x^2-5x+1$ for $-3\le x\le 5$.
(c) Using the same scale and axes, draw the graph of $y=x+6$.
(d) Estimate from your graphs, correct to one decimal place : (i) the least value of y and the value of x for which it occurs ; (ii) the solution of the equation $2x^2-5x+1=x+6$.
