question\nexpress the interval shown on the number line in interval notation.\nanswer\nattempt 1 out of 3\ninterval notation:
Answer
Explanation:
Step1: Identify the starting point
The number line has a closed dot at 8, meaning 8 is included in the interval, so we use a left bracket $[$.
Step2: Identify the direction
The arrow points right, indicating the interval extends to positive infinity $\infty$, which uses a right parenthesis $)$.
Step3: Combine into interval notation
Write the interval from the starting point to infinity.
Answer:
$[8, \infty)$
