Math Problem Statement

The entire graph of the function h is shown in the figure below. Write the domain and range of h as intervals or unions of intervals.

Solution

To analyze the graph of the function hh, we need to determine both the domain and range based on the behavior of the graph.

Domain:

The domain consists of all possible values of xx for which the function is defined. From the graph:

  • The function starts at x=4x = -4 and continues up to x=5x = 5, with a break between x=1x = -1 and x=2x = 2, where the function is not defined.
  • The points at x=4x = -4 and x=5x = 5 are open circles, indicating that these values are not included in the domain.

Thus, the domain is the union of the intervals: (4,1][2,5)(-4, -1] \cup [2, 5)

Range:

The range consists of all possible values of yy that the function takes.

  • The lowest point is at y=1y = -1 (at x=2x = -2).
  • The highest point is at y=4y = 4 (at x=4x = -4).
  • The function does not cover values between y=0y = 0 and y=1y = 1 based on the break in the graph.

Thus, the range is: [ [-1, 0] \cup [2, 4] ]

Final Answer:

  • Domain: (4,1][2,5)(-4, -1] \cup [2, 5)
  • Range: [1,0][2,4][-1, 0] \cup [2, 4]

Here are 5 related questions:

  1. How does one determine the domain and range from a graph?
  2. What is the significance of open and closed circles on a graph?
  3. How do breaks in the graph affect the domain and range?
  4. Can a function have more than one disconnected interval in its domain?
  5. What is the difference between the domain of a function and its range?

Tip: Open circles on a graph mean that the point is not included in the domain or range, while closed circles mean the point is included.
