Systems of nonlinear inequalities

Practice systems of nonlinear inequalities using point tests, curved boundaries and intersections of feasible regions. Questions progress from circle and parabola constraints to strict inequalities, disconnected sets and rational-domain restrictions. A coordinate diagram supports graphical interpretation, while multiselect items expose the difference between satisfying one condition and satisfying an entire system. Detailed explanations connect algebraic bounds with included endpoints and excluded curves. This extension set prepares you to reason about constrained models without assuming every feasible region is connected or visible in a small graphing window.
