Math Problem Statement
Sketch the graph of the given inequality: |x + 1| ≥ 6
Solution
The inequality given is:
Steps to solve:
-
Break down the absolute value inequality: The expression implies two cases:
-
Solve each case:
-
Case 1:
-
Case 2:
-
-
Combine the solutions: The inequality holds true for or .
Graphing the solution:
- Draw a number line with key points at and .
- Shade the region where (i.e., all values to the left of ) and (i.e., all values to the right of ).
- Since the inequality is greater than or equal to, include the points and with solid circles at these points.
Would you like me to sketch this graph for you, or provide additional details?
