Verified step by step guidance
1
Identify the interval notation given: \(\left(-\infty, 2\right]\). This represents all values less than or equal to 2.
Recall that \(-\infty\) is not a number but indicates the interval extends indefinitely to the left on the number line.
The parenthesis '(' next to \(-\infty\) means that \(-\infty\) is not included in the interval, which is always the case since infinity is not a real number.
The bracket ']' next to 2 means that 2 is included in the interval, so the inequality will include equality (\leq).
Rewrite the interval as an inequality: \(x \leq 2\), meaning all \(x\) values less than or equal to 2.
