Math Problem Statement

Graph the compound inequality: x >= -2 and x <= 1.

Solution

The compound inequality provided is:

x2andx1x \geq -2 \quad \text{and} \quad x \leq 1

This can be rewritten as:

2x1-2 \leq x \leq 1

Graphing the inequality:

  1. The inequality x2x \geq -2 means the value at 2-2 is included (closed circle) and extends to the right.
  2. The inequality x1x \leq 1 means the value at 11 is included (closed circle) and extends to the left.

On the number line:

  • Place a closed circle at x=2x = -2 and another closed circle at x=1x = 1.
  • Draw a line connecting these two points, representing all the values between 2-2 and 11, inclusive.

This is how the graph would look on a number line between 2-2 and 11, with closed circles at both endpoints.

Tip: When graphing inequalities, always check if the endpoints are included (closed circles) or not (open circles).
