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.

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 xx-values where the function is defined.
From the graph:

  • The function starts at x=2x = -2, but there's an open circle indicating that the function is not defined at x=2x = -2.
  • The function extends to the right indefinitely.

Thus, the domain is:
(2,)(-2, \infty)


2. Range

The range is the set of all possible yy-values of the function.
From the graph:

  • The function starts close to y=3y = -3 but with an open circle at y=3y = -3, so y=3y = -3 is not included.
  • The function continues downward (negative values), decreasing as xx increases.

Thus, the range is:
(,3)(-\infty, -3)


3. x-intercept(s)

The xx-intercepts are where the graph crosses the xx-axis (y=0y = 0).

From the graph:

  • The graph does not touch or cross the xx-axis.

Thus, the xx-intercepts are:
DNE (Does Not Exist)\text{DNE (Does Not Exist)}


4. y-intercept

The yy-intercept is where the graph crosses the yy-axis (x=0x = 0).

From the graph:

  • At x=0x = 0, the graph is located at y=4y = -4.

Thus, the yy-intercept is:
y=4y = -4


5. Function Values

Here, you are likely looking for the value of the function at a specific xx-value. For example:

  • At x=2x = -2: The open circle indicates the function is undefined, so f(2)=DNEf(-2) = \text{DNE}.
  • At x=0x = 0: As noted earlier, f(0)=4f(0) = -4.

Final Summary:

  • Domain: (2,)(-2, \infty)
  • Range: (,3)(-\infty, -3)
  • x-intercepts: DNE
  • y-intercept: y=4y = -4
  • Specific function values:
    • f(2)=DNEf(-2) = \text{DNE}
    • f(0)=4f(0) = -4

Let me know if you'd like further explanations or additional examples! Here are 5 related questions to expand on this:

  1. How can you determine a function’s domain and range from its equation?
  2. What is the difference between an open circle and a closed circle on a graph?
  3. How would you write the function if it had xx-intercepts?
  4. How does a horizontal asymptote influence the range of a function?
  5. Can a function have multiple yy-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.
