Graphing linear functions Graphing linear functions This section focuses on the key features and methods for working with linear graphs. It demonstrates how to sketch graphs from rules, derive rules ...

Linear functions, graphs and equations Linear functions are fundamental building blocks in mathematics and play a key role in solving real-world problems where the rate of change remains constant.

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Eduqas.

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function y = a x 2 + b x + c is a smooth curve with one turning point.

Often in economics a linear function cannot explain the relationship between variables. In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph ...
