Math Problem Statement

Find the domain and range for the function represented by the graph.

Solution

Let's analyze the graph to determine the domain and range.

Domain:

The domain refers to the set of all possible x-values (input values) for the function. From the graph:

  • The function includes points between x=5x = -5 and x=6x = 6, with both closed and open circles indicating certain values are included or excluded.

Analysis of Domain:

  • There is a segment from x=5x = -5 to x=2x = -2, and both points seem to be closed circles, meaning these are included.
  • Another segment appears between x=2x = 2 and x=6x = 6, where x=2x = 2 has an open circle, indicating that this value is excluded, while x=6x = 6 is included (closed circle).

Thus, the domain is: [ \text{Domain} = [-5, -2] \cup (2, 6] ]

Range:

The range refers to the set of all possible y-values (output values) for the function. From the graph:

  • The y-values range from y=4y = -4 to y=3y = 3.

Analysis of Range:

  • The function includes y=4y = -4, but there is no point at y=3y = -3 (open circle).
  • There are points at y=0y = 0, y=1y = 1, and y=3y = 3.

Thus, the range is: Range={4,0,1,3}\text{Range} = \{-4, 0, 1, 3\}

Final Answer:

  • Domain: [5,2](2,6][-5, -2] \cup (2, 6]
  • Range: {4,0,1,3}\{-4, 0, 1, 3\}

Here are 5 related questions to expand on this:

  1. How can you determine if a function is continuous from a graph?
  2. What does an open circle on a graph indicate in terms of domain and range?
  3. How does the vertical line test help in identifying functions on a graph?
  4. Can the range of a function include both individual points and intervals?
  5. What is the difference between a closed interval and an open interval?

Tip: Always observe both the x-axis and y-axis carefully, as the domain and range are about the horizontal and vertical extents of a function.
