Math Problem Statement

Have to write a equation for the vertical and horizontal adymotote cannot just be “x=1 or y=0”

Have to write an equation for the vertical and horizontal asymptote, cannot just be 'x = 1' or 'y = 0'.

Solution

The rational function given is f(x)=1x1f(x) = \frac{1}{x - 1}.

To determine the asymptotes:

  1. Vertical Asymptote (V.A.):
    A vertical asymptote occurs when the denominator of the function is zero, because the function approaches infinity near these points.

    For the function f(x)=1x1f(x) = \frac{1}{x - 1}, the vertical asymptote occurs where x1=0x - 1 = 0, which simplifies to: x=1x = 1 Therefore, the equation for the vertical asymptote is: Vertical Asymptote: x=1\text{Vertical Asymptote: } x = 1

  2. Horizontal Asymptote (H.A.):
    A horizontal asymptote occurs when xx approaches infinity or negative infinity, and we look at the behavior of the function.

    For rational functions like f(x)=1x1f(x) = \frac{1}{x - 1}, as xx tends to \infty or -\infty, the function approaches zero because the numerator is a constant (1) and the denominator grows without bound.

    Thus, the horizontal asymptote is: Horizontal Asymptote: y=0\text{Horizontal Asymptote: } y = 0

Explanation of the error messages:

  • For the Horizontal Asymptote, you wrote x = 1, which is incorrect because that is the vertical asymptote equation, not the horizontal one. The correct horizontal asymptote is y=0y = 0.

  • For the Vertical Asymptote, you wrote y = 0, which is also incorrect because the vertical asymptote relates to the value of xx, not yy. The correct vertical asymptote is x=1x = 1.

Corrected Asymptote Equations:

  • Horizontal Asymptote: y=0y = 0
  • Vertical Asymptote: x=1x = 1

Do you want further explanation on asymptotes or how to graph them?

Here are 5 questions that expand on this:

  1. How do horizontal asymptotes change when the degree of the numerator is higher than the denominator?
  2. Can a function cross its horizontal asymptote, and if so, when?
  3. How do we find oblique (slant) asymptotes?
  4. How does the graph of f(x)=1xaf(x) = \frac{1}{x - a} change as aa varies?
  5. What happens to the asymptotes if the numerator is a higher-degree polynomial?

Tip: Always check the degrees of the numerator and denominator when identifying horizontal asymptotes for rational functions.
