Math Problem Statement

Use the graph to determine the function's domain, range, x-intercepts, y-intercept, and specific function values.

Solution

Let's go through the questions and answers based on the graph.

  1. Domain: The domain refers to all possible x-values for which the function is defined. From the graph, the function spans horizontally from x=5x = -5 to x=2x = 2. Hence, the domain is:

    Domain: [5,2][-5, 2]

  2. Range: The range refers to all possible y-values that the function can take. Observing the graph, the function reaches its highest point at y=6y = 6 and its lowest point at y=5y = -5. Therefore, the range is:

    Range: [5,6][-5, 6]

  3. X-intercepts: X-intercepts are the points where the graph crosses the x-axis (i.e., where y=0y = 0). From the graph, the function touches the x-axis at x=5x = -5, x=2x = -2, and x=2x = 2. Therefore, the x-intercepts are:

    X-intercepts: x=5,2,2x = -5, -2, 2

  4. Y-intercept: The y-intercept is the point where the graph crosses the y-axis (i.e., where x=0x = 0). From the graph, we can see that the function crosses the y-axis at y=5y = 5.

    Y-intercept: y=5y = 5

  5. Function values:

    • f(3)f(-3): To find f(3)f(-3), observe the graph at x=3x = -3. The corresponding y-value is y=4y = 4, so f(3)=4f(-3) = 4.
    • f(2)f(2): To find f(2)f(2), observe the graph at x=2x = 2. The corresponding y-value is y=0y = 0, so f(2)=0f(2) = 0.

Do you need further details or have any questions on this?

Here are some additional questions related to this:

  1. How do you find the x-intercepts of a function algebraically?
  2. What is the general definition of the domain of a function?
  3. How would you determine the range of a function if the graph is not available?
  4. What is the significance of intercepts in analyzing a function's behavior?
  5. How would transformations, like shifting or stretching, affect the intercepts and domain of the function?

Tip: Always remember to express the domain and range of a function in interval notation, considering whether endpoints are included or excluded.
