Quadratic graph lines are U- or Õˆ-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.
The Doodle shows how the parabola changes with different numbers, making learning math fun and interactive for students.
