-2 < x <= 9.....use [ ] when there is an equal sign....use ( ) when there is not an equal sign.

(2 , 9 ] ....greater then 2, less then or equal to 9

The given compound inequality in Interval Notation is

 -2 < x ≤9

From left side the notation is , semi open(either < or >) and from right side the interval notation is closed(either ≤ or ≥).

So, it can be represented as→(-2,9]

Option C→(−2,9]
