Transcript text: Plot the set of integers indicated by the inequality. Be sure to plot every point that satisfies the inequality.
\[
|a| \geq 2
\]
Solution
Solution Steps
Step 1: Understand the Inequality
The given inequality is \( |a| \geq 2 \). This means that the absolute value of \( a \) must be greater than or equal to 2.
Step 2: Interpret the Absolute Value
The absolute value \( |a| \geq 2 \) implies that \( a \) can be either greater than or equal to 2 or less than or equal to -2. Mathematically, this can be written as:
\[ a \geq 2 \quad \text{or} \quad a \leq -2 \]
Step 3: Identify the Integer Solutions
We need to find the integer values of \( a \) that satisfy the inequality. The integers that satisfy \( a \geq 2 \) are \( 2, 3, 4, \ldots \). The integers that satisfy \( a \leq -2 \) are \( -2, -3, -4, \ldots \).
Final Answer
The set of integers that satisfy the inequality \( |a| \geq 2 \) are:
\[ \{ \ldots, -4, -3, -2, 2, 3, 4, \ldots \} \]
On the number line, you would plot points at:
\[ \ldots, -4, -3, -2, 2, 3, 4, \ldots \]
