All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

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 diagram ...

Most people finish studying mathematics without understanding the beauty of mathematical formulas, but there are some people who can feel that only a few "mathematics are beautiful", and how can we ...

Google's latest animated Doodle celebrates the quadratic equation, transforming its homepage into an interactive classroom.
