Answer:
(-9, 2]
Step-by-step explanation:
First, you have to find the interval that is the solution. Then you can write it using the appropriate notation.
-32 < 3x -5 ≤ 1
-27 < 3x ≤ 6 . . . . . . add 5
-9 < x ≤ 2 . . . . . . . . divide by 3
The open end of an interval is delimited using a curve bracket (parenthesis). The closed end of an interval is delimited using a square bracket.
This half-open interval will have a curved bracket on the left side, and a square bracket on the right side:
(-9, 2]
