All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth curve with one turning point. The turning ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

Google's latest animated Doodle celebrates the quadratic equation, transforming its homepage into an interactive classroom. This visual tribute highlights the formula's components and solutions, ...
