Math Problem Statement

Consider the function in the graph. Determine the relative maximum, relative minimum, intervals of increase and decrease, domain, and range.

Solution

Let me extract the information from the graph and the prompts in your image to solve the questions. One moment please!### Analysis of the Graph and Questions:

1. Relative Maximum

  • The relative maximum occurs where the graph peaks locally. From the graph, the highest local peak appears at x=3x = 3, and the function value there is approximately y=4y = 4.
  • Answer:
    • Relative maximum = 4 at x=3x = 3.

2. Relative Minimum

  • The relative minimum occurs where the graph dips locally. From the graph, the lowest local dip is at x=2x = -2, and the function value there is approximately y=6y = -6.
  • Answer:
    • Relative minimum = -6 at x=2x = -2.

3. Intervals of Increase

  • The function is increasing wherever the slope of the graph is positive (going uphill).
    • Increasing interval: (2,3)(-2, 3) (from the minimum at x=2x = -2 to the maximum at x=3x = 3).
  • Answer:
    • Increasing on (2,3)(-2, 3).

4. Intervals of Decrease

  • The function is decreasing wherever the slope of the graph is negative (going downhill).
    • Decreasing intervals:
      • (,2)(-\infty, -2) (from left to the minimum at x=2x = -2),
      • (3,)(3, \infty) (from the maximum at x=3x = 3 to the right).
  • Answer:
    • Decreasing on (,2)(-\infty, -2) and (3,)(3, \infty).

5. Domain

  • The graph extends infinitely in both the left and right directions (all xx-values are included).
  • Answer:
    • Domain is (,)(-\infty, \infty).

6. Range

  • The graph spans vertically from its lowest point (y=6y = -6) to its highest point (y=4y = 4), covering all values in between.
  • Answer:
    • Range is [6,4][-6, 4].

Final Answers:

  1. The function has a relative maximum of 4 at x=3x = 3.
  2. The function has a relative minimum of -6 at x=2x = -2.
  3. The function is increasing on the interval (2,3)(-2, 3).
  4. The function is decreasing on the intervals (,2)(-\infty, -2) and (3,)(3, \infty).
  5. The domain of the function is (,)(-\infty, \infty).
  6. The range of the function is [6,4][-6, 4].

Do you want a detailed breakdown of any of the steps?
Here are five questions to expand on this:

  1. How do you determine intervals of increase and decrease from a graph?
  2. What does "domain" mean in the context of functions?
  3. How do relative maxima and minima relate to the derivative of a function?
  4. Can there be more than one relative maximum or minimum in a function?
  5. What is the significance of the range for real-world applications?

Tip: Always analyze a graph systematically, starting with extrema, intervals, and the overall behavior of the function!
