Math Problem Statement

F(x)=1/x-2+3

Solution

The function you provided is:

F(x)=1x2+3F(x) = \frac{1}{x - 2} + 3

This is a rational function where the variable xx appears in the denominator of the first term. Let's break it down:

  1. The term 1x2\frac{1}{x - 2} represents a rational function with a vertical asymptote at x=2x = 2 (because the denominator becomes zero at x=2x = 2, which makes the function undefined).
  2. The constant +3+3 shifts the entire graph of the function upwards by 3 units.

Key features of the function:

  • Vertical asymptote: at x=2x = 2.
  • Horizontal asymptote: Since the constant term is +3+3, the horizontal asymptote is y=3y = 3, because as xx becomes very large or very small, 1x2\frac{1}{x - 2} approaches 0.
  • Domain: All real numbers except x=2x = 2, i.e., (,2)(2,)(-\infty, 2) \cup (2, \infty).

Would you like to go into further details or clarify any part of this?

Here are 5 related questions to expand this concept:

  1. How would the graph change if we altered the constant 3 to another number?
  2. What is the behavior of the function as x2x \to 2 from the left and right sides?
  3. Can we calculate the derivative of this function?
  4. How would you find the x-intercept of this function?
  5. What is the effect of modifying the denominator to xax - a instead of x2x - 2?

Tip: For rational functions like these, always identify vertical and horizontal asymptotes, as they provide key information about the function's behavior.
