The graph of \(y = f(x)\) where \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing equations as functions in the form \(f(x)\) is useful when applying translations and reflections to ...

exponential and circle graphs. Their equations can be used to plot their shape. Transformation of curves - Higher - Edexcel Functions of graphs can be transformed to show shifts and reflections.
