Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

My readers did it again! They submitted 28 entries of ways to visualize the table in Figure 1. This part of the Graph Makeover Contest was much more challenging than the redesign of the donut chart, ...
