The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the \(y\)-axis. The shape has been reflected in ...

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 \(x = 3\).
