Answer: y ≥ −x^2 − 9x − 18
Step-by-step explanation:
The boundary of the related parabola is solid (not dashed), so the inequality symbol must be ≤ or ≥. The region above the parabola is shaded, so the inequality symbol must be ≥, not ≤. Therefore, the quadratic inequality that produces the graph is y ≥ −x2 − 9x − 18.
