I assume the scale is called x.
We then notice the interval for x is [-3 ; 5[
we observe that in -3 there is a red dot that indicate it is a part of the interval, unlike with 5 where it is not filled, in other words... it is not a part of the interval.
Now we set up an inequality... we know that x have to be bigger or equal to -3 so we write:
-3<=x
Now we see on the other side that it is going highest to 5 so we can write this:
x<5 (remember 5 is not a part of it)
Put both inequalities together and we get:
-3<=x<5
