Concept explainers
To sketch:
The graph of the solution set of the system of inequalities
Explanation of Solution
Given:
The equation
Concept used:
Replace the inequality sign and sketch the graph of the resulting equation (use a dashed line for < or > and a solid line for
Test one point in each of the region formed by the graph
If the point satisfies the inequality then shade the entire region to denote that every point in the region satisfies the inequality
Calculation:
Test one point in each of the region formed by the graph
If the point satisfies the inequality then shade the entire region to denote that every point in the region satisfies the inequality
