The graph of a quadratic function is a parabola. It is a curved line shaped like the alphabet 'U' or an inverted 'U'. A parabola has a vertex, which is the point at the apex of the 'U' curve (that is the bottom most or the top most point). A parabola generally crosses the x-axis at two points, known as the x-intercepts.
In order to graph a quadratic function, the coordinates of the vertex and x-intercepts of the parabola must be known. In addition, you may require to get some more points on either side of the axis of symmetry.
There are two different approaches to graphing a quadratic according to the form of the quadratic function.
