[Foundation and Higher] Find approximate quadratic solutions using a graph.

[Foundation and Higher] Find approximate quadratic solutions using a graph. is assessed within Solving equations and inequalities. Quadratic graphical solutions use a parabola, so the answer may involve two roots, one repeated root, or no real crossing. The solution should state which line or axis is being intersected, then read each x-value from the graph to an appropriate accuracy. This is not the same as solving a linear equation from a graph because the curved shape changes the number and position of solutions. For exam answers, show the chosen representation, calculation step or graph reading before giving the final value.
