Key Concepts

System of Inequalities

A system of inequalities involves two or more inequalities that are considered simultaneously. The solution to the system is the set of all points that satisfy every inequality in the system. Graphically, this is represented by the overlapping (intersection) region of the individual inequality graphs.

Quadratic Inequalities

Quadratic inequalities are inequalities where the expressions involved are quadratic, meaning they include terms with x^2. These inequalities are solved by identifying the corresponding quadratic equation, determining its key features like the vertex and intercepts, and then deciding which regions satisfy the inequality based on the direction of the parabola.

Graphing Parabolic Functions

Graphing parabolic functions involves drawing the curve represented by a quadratic equation. Essential steps include determining the vertex, axis of symmetry, and the direction in which the parabola opens. These features are crucial in accurately plotting the boundary of the inequality and understanding the shape and position of the region on a coordinate plane.

Intersection of Regions

The intersection of regions is a key concept when working with systems of inequalities. After graphing each inequality separately, the solution to the system is found by identifying the area where all the individual shaded regions overlap. This common region represents all solutions that satisfy every inequality in the system.

In Problems 35-42, graph each system of inequalities. $\left\{\begin{array}{l}y+x^2 \leq 1 \\ y \geq x^2-1\end{array}\right.$
