Math Problem Statement

Domain and range

Solution

To determine the domain and range of the piecewise linear function shown in the image, let's analyze the graph step by step.

Domain:

The domain of the function is the set of all possible xx values for which the function is defined. Based on the graph:

  • The graph starts at x=5x = -5 and ends at x=5x = 5.
  • Therefore, the domain is all xx values between 5-5 and 55, inclusive.

Domain: Domain=[5,5]\text{Domain} = [-5, 5]

Range:

The range of the function is the set of all possible yy values that the function can take.

  • The lowest yy value on the graph is 6-6, which occurs at both x=5x = -5 and x=5x = 5.
  • The highest yy value occurs at y=4y = 4 when xx is between 2-2 and 1-1.

Range: Range=[6,4]\text{Range} = [-6, 4]

Summary:

  • Domain: [5,5][-5, 5]
  • Range: [6,4][-6, 4]

  1. What is a piecewise function, and how is it defined?
  2. How do you determine the slope of each segment in the graph?
  3. Can the domain and range of a function be represented in set notation?
  4. How would the domain and range change if the graph were extended?

Tip: Always pay close attention to the endpoints of the graph when determining the domain and range—they often indicate whether the intervals should be open or closed.
