The coordinates of the turning point and the equation of the line of symmetry can be found by writing ... 3)\) and so the graph will cross the \(x\)-axis at \(x = -1\) and \(x = 3\).

The line \(y = 1\) is a horizontal line which passes through 1 on the \(y\)-axis. The shape has been reflected in the line \(y = 1\). The equation of a straight line graph has the form \(y = mx ...
