Answer:
[-3,5]
Step-by-step explanation:
Interval notation is a shorthand way of writing and interval of values. To describe an interval, imagine the two endpoints on the number-line. Then, list the two endpoint values, leftmost point from the number-line first, separated by a comma. Lastly, include the appropriate brackets for each endpoint:
- Only two brackets total will be used for each interval, a bracket to start it, and one bracket to end it.
- If a number is included, a square bracket should be used -- either "[" or "]"
- If the endpoint number is not meant to be included, a 'curved bracket' (which we usually just call a parenthesis) should be used -- either "(" or ")"
For our situation, the two endpoints are -3 and 5. -3 is to the left of 5 on the number-line, so -3 should be listed first

Lastly, the directions say "including -3 and 5", so both endpoints should be included.
- To include the -3 on the left, we'll use "["
- To include the 5 on the right, we'll use "]"
The final result for the interval is [tex][-3,5][/tex]
