On this graph, when finding the range, you see the top of the graph contains BOTH an open and a closed circle. Which one overrides the other?

• Closed circle overrides meaning the value of y=1 is included

• Open circle overrides meaning the value of y=1 is not included

• Closed circle overrides meaning the value of y=1 is not included

• Open circle overrides meaning the value of y=1 is included
