The graph of \(y = x^2 + x − 6 \) crosses the \(x\)-axis at \(x = -3\) and \(x = 2\). The coefficient of \(x^2\) is positive, so the graph will be a positive U-shaped curve with a turning point ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative.

The extreme readings of 1998-2001 stayed within the dashed-line channel, but the past six years’ closing valuations are all beyond it. In three of those years — 2021, 2023 and 2024 — price to book ...
