The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic ... the completed square form of the equation. So the graph of \(y = x^2 ...

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