Math Problem Statement

graph the function. Find the zeros of each function and the x- and y-intercepts of each graph, if any exist. From the graph, determine the domain and range of each function, list the intervals on which the function is increasing, decreasing or constant, and find the relative and absolute extrema, if they exist. f(x) = |2 − x| / 2 − x

Solution

Here is the graph of the function f(x)=2x2xf(x) = \frac{|2 - x|}{2 - x}. It shows the following:

  • The function is constant and equals 1 for x<2x < 2.
  • The function is constant and equals -1 for x>2x > 2.
  • There is a discontinuity at x=2x = 2, where the function is undefined.

Summary:

  1. Zeros: None.
  2. X-intercept: None.
  3. Y-intercept: (0,1)(0, 1).
  4. Domain: (,2)(2,)(-\infty, 2) \cup (2, \infty).
  5. Range: {1,1}\{-1, 1\}.
  6. Increasing/Decreasing Intervals: Constant on both (,2)(-\infty, 2) and (2,)(2, \infty).
  7. Extrema: None (no relative or absolute maxima/minima).

  1. How can you interpret the jump at x=2x = 2 mathematically?
  2. What happens if we modify the denominator slightly, such as 22x2 - 2x?
  3. How would this function behave with different absolute values in the numerator?
  4. What is the difference between a removable and a non-removable discontinuity?
  5. How does this function compare to a step function?

Tip: Discontinuities like this one are called "jump discontinuities," where the function value jumps between two different levels.
