Math Problem Statement
Use the graph of the function to find its domain and range. Write the domain and range in interval notation.
Solution
The graph shows a function with a starting point at and appears to extend indefinitely upwards as . Based on this, I can determine the domain and range.
Domain:
- The graph starts at (where there is an open circle indicating that this point is not included in the domain).
- The function extends to the right, without bound as .
Thus, the domain is:
Range:
- The graph starts at and rises without bound.
- Since the open circle is at , the function does not include this value but starts immediately above it.
Thus, the range is:
Conclusion:
- Domain:
- Range:

- How do you determine the range of a function when looking at its graph?
- How does the graph's increasing and decreasing behavior affect the range?
Tip: When analyzing a graph, always pay close attention to open and closed circles, as they indicate whether specific points are included in the function's domain or range.
