The shape has been reflected in the line \(y = 1\). The equation of a straight line graph has the form \(y = mx + c\), where \(m\) is the gradient and \(c\) is where the line crosses the \(y\)-axis.

The coefficient of \(x^2\) is positive, so the graph will be a positive U-shaped curve with a turning point and line of symmetry at \(x = −0.5\). To find where the graph crosses the \(y\)-axis ...
