Respuesta :
-1 to 3 use colored points because they have an equal sign, so they should have a beginning and end.
Answer:
n ≥ -1 or n ≤ 3
Combined:
-1 ≤ n ≤ 3
Since the inequalities are ≤, it'll be a closed circle
The closed circle will start AT -1 and another closed circle will end at 3
I'll attach an image, so you can see
