Graphs can also be used to evaluate more complex expressions, such as those involving multiple functions or operations. The ...

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 \(a \textgreater 0 \) ...

Problem Type 1 typically involves graphing piecewise functions with relatively simple sub-functions, such as linear functions, constants, or simple quadratics. Here’s a structured approach to graph ...

Practice how to recognise and determine the equation of a quadratic function from its graph ahead of your National 5 Maths exam with this interactive maths quiz. The equation of a a quadratic function ...
