### All Quadratic Graphs are U shaped (TANTON Mathematics)

The equation y = ax^2 + bx + c is the equation of a U-shaped graph (x^2) plus the equation of a line (bx+c). If one pauses for a moment, it is not at all obvious that these two shapes added together give another U shape! We explain why in this follow-up video to graphing quadratics. [p.s. I was human again! There is a small error near the very end of the video. It is not a big deal, but for extra points, can you spot it??]
