Answer 1

I can't see the graph you mean. Please either upload the image or describe the graph (the highest and lowest points and whether any endpoints are open or closed).

How to determine the range from the graph:
- The range is the set of all y-values the graph attains.
- Find the lowest y-value on the graph and the highest y-value.
- If the graph continues without bound upward or downward, the range will be of the form y ≥ a or y ≤ b.
- If the lowest and highest are finite and included, the range is a closed interval a ≤ y ≤ b; if an endpoint is excluded use a strict inequality or parentheses.
- Pay attention to open dots (excluded) vs closed dots (included).

If you upload or describe the graph I’ll pick the correct option from the list.
