Math Problem Statement

Graph the compound inequality: x ≥ -4 and x < -1

Solution

The problem asks to graph the compound inequality:

x4andx<1x \geq -4 \quad \text{and} \quad x < -1

Steps to graph the inequality:

  1. The inequality x4x \geq -4 means that xx includes -4 and all values greater than -4. This is represented by a closed circle at x=4x = -4 and a line extending to the right (greater values).
  2. The inequality x<1x < -1 means that xx includes all values less than -1, but not -1 itself. This is represented by an open circle at x=1x = -1 and a line extending to the left (less than -1).

Graph Description:

  • Place a closed circle at x=4x = -4.
  • Place an open circle at x=1x = -1.
  • Shade the line between x=4x = -4 and x=1x = -1.

This graph represents all the values of xx between 4-4 and 1-1, including 4-4 but not 1-1.

Would you like further details on inequalities or graphing? Here are five related questions:

  1. What is the difference between a closed and open circle in inequality graphs?
  2. How do you solve compound inequalities with "and" versus "or"?
  3. Can a compound inequality have overlapping solution sets?
  4. What happens if an inequality involves absolute values?
  5. How do you graph compound inequalities on a number line?

Tip: Always pay attention to whether inequalities include the endpoints (use closed circles) or exclude them (use open circles).
