express the interval shown on the number line in interval notation.\nanswer attempt 1 out of 2\ninterval notation:
Answer
Explanation:
Step1: Identify the endpoint value
The endpoint on the number - line is at $x = - 6$.
Step2: Determine the type of interval
The arrow points to the left and the dot at $x=-6$ is filled, indicating that the interval includes $-6$ and all numbers less than $-6$.
Step3: Write in interval notation
We use negative infinity $(-\infty)$ and a square - bracket for the included endpoint. The interval notation is $(-\infty,-6]$.
Answer:
$(-\infty,-6]$
