6 (a) Complete the table for y= x^2/2 -3x+2. (b) Draw the graph of y= x^2/2 -3x+2 for -1 =< x =< 7. (c) By drawing a tangent, estimate the gradient of the curve at x = 1.5 . (d) Complete these inequalities to describe the range of values of x where y =>0. (e) (i) On the same grid, draw the line 4y + 3x = 12 . (ii) The x-coordinates of the points of intersection of this line and the curve are the solutions of the equation 2x^2 + Ax + B = 0 . Find the value of A and the value of B.
