A. Zero of the numerator
B. Zero of the denominator
C. Y = 0 if n <d
D. (X, 0)
E. (0, Y)
-
x-intercept
-
y-intercept
-
Zero of the function
-
Vertical asymptote
-
Horizontal asymptote
Solution
Let's match the items from Column A with the appropriate items from Column B.
Here is the reasoning:
-
X-intercept: This occurs when , which happens when the numerator of the function equals zero. This is a point of the form .
- So, 1 → D (X, 0).
-
Y-intercept: This occurs when , meaning the function is evaluated at , leading to a point of the form .
- So, 2 → E (0, Y).
-
Zero of the function: This also happens when , which again is when the numerator is zero.
- So, 3 → A Zero of the numerator.
-
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.
-
Horizontal asymptote: A horizontal asymptote exists when the degree of the numerator is less than the degree of the denominator, and the function approaches as goes to infinity.
- So, 5 → C Y = 0 if n < d.
Final Matching:
- 1 → D
- 2 → E
- 3 → A
- 4 → B
- 5 → C
Would you like more details or have any questions about this matching? Here are some related questions to expand your understanding:
- What happens to the graph of a function at a vertical asymptote?
- How do you find the x-intercept of a rational function?
- Can a function have more than one horizontal asymptote?
- What does it mean for a function to have no x-intercept?
- 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.
