Math Problem Statement

Use the graph of the function to find its domain and range. Write the domain and range in interval notation.

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 x=1x = -1 and appears to extend indefinitely upwards as xx \to \infty. Based on this, I can determine the domain and range.

Domain:

  • The graph starts at x=1x = -1 (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 xx \to \infty.

Thus, the domain is: (1,)(-1, \infty)

Range:

  • The graph starts at y=5y = -5 and rises without bound.
  • Since the open circle is at y=5y = -5, the function does not include this value but starts immediately above it.

Thus, the range is: (5,)(-5, \infty)

Conclusion:

  • Domain: (1,)(-1, \infty)
  • Range: (5,)(-5, \infty)

Would you like more details or have any questions?

Here are 5 related questions for further practice:

  1. What is the significance of the open circle on the graph at (1,5)(-1, -5)?
  2. How would you describe the behavior of the function as xx \to \infty?
  3. What would the domain and range be if the circle were closed at (1,5)(-1, -5)?
  4. How do you determine the range of a function when looking at its graph?
  5. 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.
