How to graph Quadratic Functions - what are Parabolas?
In this part I will explain to you how to graph Quadratic Equations. A quadratic equation is an equation in which the highest power of x is two. x^2 + 3x - 7 for instance is an example of a quadratic equation for the highest power of x is two. When we graph a quadratic function we ALWAYS get a beautiful symmetrical curve with one line of symmetry (like the water fountain on the picture). We call the graph of a quadratic function a Parabola. Study the following videos during your maths revision in which I will explain to you all you need to know about graphing quadratic functions to pass your IGCSE GCSE Maths exam. Make sure to study all the activities and example questions for in each video I will explain something new you need to know about quadratic equations.
