Which inequality describes the shaded region? Task 1
Identify At how many points does the boundary curve cross the x-axis? Task 2
Identify Is the origin (0, 0) inside the shaded region? Task 3
Identify Start with Shaded Regions to see how inequalities like x² + y² < r² fill a circle on the graph.
Tip: The boundary curve uses = (equality), while < or > determines which side gets shaded. Dashed lines mean strict inequality, solid lines mean ≤ or ≥.
