what is the domain and range in interval notation

Solution

The graph provided depicts a piecewise function that consists of two linear segments. Let's determine the domain and range in interval notation.

Domain:

The domain is the set of all possible xx-values for which the function is defined.

  • The first segment starts at x=8x = -8 and continues to x=2x = 2.
  • The second segment starts at x=2x = 2 and extends indefinitely to the right.

The function is defined for all xx-values from 8-8 to infinity, with a transition at x=2x = 2.

Thus, the domain in interval notation is: Domain=[8,)\text{Domain} = [-8, \infty)

Range:

The range is the set of all possible yy-values that the function takes.

  • The first segment begins at y=8y = -8 (when x=8x = -8) and ends at y=3y = -3 (when x=2x = 2).
  • The second segment starts at y=3y = -3 (when x=2x = 2) and increases indefinitely.

Therefore, the function covers all yy-values from 8-8 to infinity.

Thus, the range in interval notation is: Range=[8,)\text{Range} = [-8, \infty)

Summary:

  • Domain: [8,)[-8, \infty)
  • Range: [8,)[-8, \infty)

Would you like to go over any specific details, or do you have any further questions?

Here are five related questions that could be useful:

  1. How would the domain and range change if the function had a vertical asymptote?
  2. What would the domain and range look like if the graph included a hole or discontinuity?
  3. How do you find the domain and range for a quadratic function?
  4. What happens to the range if the function is reflected across the x-axis?
  5. How can you determine if a function is one-to-one based on its graph?

Tip: When working with piecewise functions, always check each segment individually to determine the overall domain and range.
