As a quadratic function, you will find that the symmetry axis is constant, x = 2, the opening is getting bigger and bigger, (if you go up, the opening at the back is all up, if you go down, the opening at the back is all down), and the intersection with the X axis will expand more and more outward, so, as mentioned above, you can draw a sketch and try. Of course, don't make a mistake!

I only drew the case where the back opening is upward, and the other is that the opening starts from the second parabola and opens downward in turn, and the intersection point is the same as this picture! There is a little error in this picture, the distance between any two intersections is the same, both are 2, and the innermost two intersections in my picture are far away, please forgive me!
