Question

What is the Interval notation for this

Answer 1

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:
