Question

Which interval notation represents the set of all numbers from -9 to 0, inclusive?

Answer 1

Answer:

[-9,0]

Step-by-step explanation:

You use brackets to indicate that the numbers, in this case -9 and 0, are included in the interval.

You use parentheses to indicate that the numbers are excluded from the interval.

Since we want to include the numbers in the interval, we use the brackets.

The answer is [-9,0]
