Math Problem Statement

solve and draw the graph

Solve and draw the graph of the function f(x) = (2 - x) / [(x - 1)√(x - 2)^2].

Solution

Here is the graph of the function f(x)=2x(x1)(x2)2f(x) = \frac{2 - x}{(x - 1)\sqrt{(x - 2)^2}}. The graph has vertical asymptotes at x=1x = 1 (shown in red) and x=2x = 2 (shown in green), where the function becomes undefined.

Key observations:

  • At x=1x = 1 and x=2x = 2, the function has vertical asymptotes.
  • As xx approaches 1 from both sides, f(x)f(x) tends to infinity or negative infinity.
  • Around x=2x = 2, there is a discontinuity since the denominator involves (x2)(x - 2).

Would you like more details on the behavior of the function near these asymptotes or other properties?

Here are 5 questions related to this function:

  1. What happens to the function as xx \to \infty?
  2. How does the function behave between the two asymptotes at x=1x = 1 and x=2x = 2?
  3. What would the graph look like if the denominator didn't have the square root?
  4. How does this function behave for negative values of xx?
  5. Can the function have any real roots where f(x)=0f(x) = 0?

Tip: When analyzing rational functions, always check for vertical and horizontal asymptotes by studying the behavior of the function as xx approaches the critical points.
