Math Problem Statement

Identify the function as increasing or decreasing. Using the data in the table, on which interval is the function increasing?

Solution

From the given table and the problem:

The table shows the xx and yy values, and the task is to identify where the function yy is increasing.

We determine whether the function is increasing or decreasing by analyzing how the yy-values change as xx-values increase.

Steps:

  1. Look at the table row by row:
    • From x=3x = -3 to x=2x = -2, yy decreases (6 → 0): Decreasing.
    • From x=2x = -2 to x=1x = -1, yy decreases (0 → -4): Decreasing.
    • From x=1x = -1 to x=0x = 0, yy decreases (-4 → -6): Decreasing.
    • From x=0x = 0 to x=2x = 2, yy increases (-6 → -4 → 0): Increasing.
    • From x=2x = 2 to x=4x = 4, yy increases (0 → 6): Increasing.

Answer: The intervals where yy increases are:

  • 0<x<20 < x < 2 (option B) and
  • 2<x<42 < x < 4 (option A).

If asked for a single answer from the provided options, the correct interval where the function increases is B: 0<x<20 < x < 2.


Would you like further clarification or a detailed explanation of this? Here are some additional related questions:

  1. How can we distinguish increasing and decreasing intervals mathematically?
  2. Why is the function not considered increasing for x<0x < 0?
  3. What are other methods to find increasing/decreasing intervals (like derivatives)?
  4. Can this table represent a continuous function? Why or why not?
  5. How would we analyze the graph of this function if plotted?

Tip: Always focus on comparing the change in yy-values relative to the xx-values to assess the trend of a function effectively!
