Complete the table below, for the function y =2x² + 4x - 3.

a) Complete the table below, for the function y =2x² + 4x - 3.

b) On the grid provided, draw the graph of y=2x² + 4x - 3 for -4<= x<= 2 and use the graph to estimate the roots of the equation to 1 decimal place.

c) In order to solve graphically 2x² + x – 5 = 0, a straight line must be drawn to intersect the curve y = 2x² + 4x – 3. Determine the equation of the straight line and draw it, hence obtain the roots of the equation 2x² + x - 5 = 0 to 1 decimal place.
