.

Column A

Column B

A. Zero of the numerator

B. Zero of the denominator

C. Y = 0 if n <d

D. (X, 0)

E. (0, Y)

  1. x-intercept

  2. y-intercept

  3. Zero of the function

  4. Vertical asymptote

  5. Horizontal asymptote

Solution

Let's match the items from Column A with the appropriate items from Column B.

Here is the reasoning:

  1. X-intercept: This occurs when y=0y = 0, which happens when the numerator of the function equals zero. This is a point of the form (x,0)(x, 0).

    • So, 1 → D (X, 0).
  2. Y-intercept: This occurs when x=0x = 0, meaning the function is evaluated at x=0x = 0, leading to a point of the form (0,y)(0, y).

    • So, 2 → E (0, Y).
  3. Zero of the function: This also happens when y=0y = 0, which again is when the numerator is zero.

    • So, 3 → A Zero of the numerator.
  4. Vertical asymptote: A vertical asymptote occurs when the denominator of a rational function is zero (but the numerator is not zero).

    • So, 4 → B Zero of the denominator.
  5. Horizontal asymptote: A horizontal asymptote exists when the degree nn of the numerator is less than the degree dd of the denominator, and the function approaches y=0y = 0 as xx goes to infinity.

    • So, 5 → C Y = 0 if n < d.

Final Matching:

  1. 1 → D
  2. 2 → E
  3. 3 → A
  4. 4 → B
  5. 5 → C

Would you like more details or have any questions about this matching? Here are some related questions to expand your understanding:

  1. What happens to the graph of a function at a vertical asymptote?
  2. How do you find the x-intercept of a rational function?
  3. Can a function have more than one horizontal asymptote?
  4. What does it mean for a function to have no x-intercept?
  5. How do you determine the behavior of a rational function near its vertical asymptotes?

Tip: The degrees of the numerator and denominator in a rational function determine the existence and location of horizontal asymptotes.
