Math Problem Statement
Use the given graph to determine the function's domain, range, x-intercept(s), y-intercept, and function values. Use interval notation for interval solutions. If multiple solutions exist, use a comma-separated list to enter the solutions. If a solution does not exist, enter DNE.
Solution
Let's analyze the given graph step by step:
1. Domain
The domain refers to all possible -values where the function is defined.
From the graph:
- The function starts at , but there's an open circle indicating that the function is not defined at .
- The function extends to the right indefinitely.
Thus, the domain is:
2. Range
The range is the set of all possible -values of the function.
From the graph:
- The function starts close to but with an open circle at , so is not included.
- The function continues downward (negative values), decreasing as increases.
Thus, the range is:
3. x-intercept(s)
The -intercepts are where the graph crosses the -axis ().
From the graph:
- The graph does not touch or cross the -axis.
Thus, the -intercepts are:
4. y-intercept
The -intercept is where the graph crosses the -axis ().
From the graph:
- At , the graph is located at .
Thus, the -intercept is:
5. Function Values
Here, you are likely looking for the value of the function at a specific -value. For example:
- At : The open circle indicates the function is undefined, so .
- At : As noted earlier, .
Final Summary:
- Domain:
- Range:
- x-intercepts: DNE
- y-intercept:
- Specific function values:
Let me know if you'd like further explanations or additional examples! Here are 5 related questions to expand on this:
- How can you determine a function’s domain and range from its equation?
- What is the difference between an open circle and a closed circle on a graph?
- How would you write the function if it had -intercepts?
- How does a horizontal asymptote influence the range of a function?
- Can a function have multiple -intercepts? Why or why not?
Tip: Open circles on graphs indicate that the function is undefined at that point, so always exclude them from the domain and range.
