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 ...

In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...

Construction of the Tangent to a Parabola 2.1 An applet illustrating how the tangent ... graphs with corners which I talked about in lecture. The tangent line to a graph does not exist at a corner.
