Heya user☺☺

The line is closed at -3 and open at 1

so, x will be.....

-3 smaller than or equal to x smaller than 1.

So, option a is correct.

Hope it works☺☺

Answer:

A. –3 ≤ x < 1

Step-by-step explanation:

The coloured circle in -3, indicates that value as part of the interval. On the other hand the white circle in 1, indicates that value is not part of the interval.

The math signs that indicates this are ≤ when the value is being included, and < when the values is being excluded.
