A curve has an equation y = 2x2 – 5x + 12a.      Write y = 2x2 – 5x + 12 in the form a(x + m)2 + nb.      Find the coordinates of the minimum point of the graph. c.      Does the graph of y = 2x2 – 5x + 12, cross the x-axis? If yes, then find the coordinates of the point of intersection.a. y = 2(x - 5/4)2 + 71/8b. (5/4, 71/8)c. No
