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.

(If a were zero, you would have a linear equation.) Through this equation, you can identify the vertex, axis of symmetry and the direction in which the parabola opens. Follow these steps to draw a ...
