For this case we must indicate the inequality represented in the graph.
It is noted that we have a closed point at -1, so the inequality at that point contains equality and is represented by "[". On the other hand, we observe an open point at +3, so inequality does not include equality (does not include +3) and is represented as ")".
So, the interval of the graph is:
[tex][-1,3)[/tex]
This is equivalent to:
[tex]-1 \leq t <3[/tex]
Answer:
Option B
