Heyy help pleaseee :)

Which polynomial function has x intercepts -1, 0, and 2 and passes through the point (1, -6)

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3
