Why are all Quadratic Graphs U shaped?
The equation y = ax2 + bx + c is the equation of a U-shaped graph (x2) 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.
