For this case, what we are going to do is verify in which points the function is equal to zero. We have the points are: x = (-b +/- root (b ^ 2 -4 * a * c)) / (2 * a) We substitute the values in the equations shown and verify that the equality is met. For y = 2x2 + 8x - 5 x1 = -2-root (13/2) x2 = root (13/2) - 2 These roots coincide with the cut points of the graph on the x axis. Answer: The equation is: y = 2x2 + 8x - 5 option 4
