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.

Exponential graphs are graphs in the form \(\text{y = k}^x\). These graphs increase rapidly in the \({y}\) direction and will never fall below the \({x}\)-axis.
