Math Problem Statement

Use the graph of f to determine intervals where f is increasing and where f is decreasing.

Solution

To solve the problem, we'll analyze the graph provided.

Step 1: Determine where the function is increasing.

A function is increasing on an interval if, as xx moves from left to right, the function's values (i.e., yy-values) are increasing. This happens when the graph is sloping upwards.

From the graph:

  • The function increases from x=6x = -6 to x=2x = -2.
  • The function also increases from x=2x = 2 to x=4x = 4.

Thus, the intervals where the function is increasing are (6,2)(-6, -2) and (2,4)(2, 4).

Step 2: Determine where the function is decreasing.

A function is decreasing on an interval if, as xx moves from left to right, the function's values are decreasing. This happens when the graph is sloping downwards.

From the graph:

  • The function decreases from x=2x = -2 to x=2x = 2.
  • The function also decreases from x=4x = 4 to x=6x = 6.

Thus, the intervals where the function is decreasing are (2,2)(-2, 2) and (4,6)(4, 6).

Final Answers:

  1. For increasing intervals (Part A): The answer is (6,2)(-6, -2) and (2,4)(2, 4).
  2. For decreasing intervals (Part B): The answer is (2,2)(-2, 2) and (4,6)(4, 6).

  2. How does the derivative of a function relate to its increasing or decreasing behavior?
  3. Can a function be increasing or decreasing on an open interval?
  4. How would you describe a function that is neither increasing nor decreasing on an interval?
  5. How do you find the maximum and minimum points on the graph of a function?

Tip: When analyzing a graph for increasing and decreasing intervals, always check the slopes and note where they change sign (from positive to negative or vice versa).
