Math Problem Statement
Solution
The image you've uploaded contains a table with rational functions and associated details such as -intercept, -intercept, zeros of the function, vertical asymptote, and horizontal asymptote. Let’s go over the first function provided in the table:
Function 1:
We need to calculate the following:
-
-intercept: The -intercept is found by setting (i.e., solving for when ).
This occurs when the numerator is zero, so:
-
-intercept: The -intercept is found by setting and evaluating .
-
Zeros of the function: The zeros of the function are the values of where , which we already calculated for the -intercept:
-
Vertical asymptote: A vertical asymptote occurs where the denominator is zero, so: Therefore, there is a vertical asymptote at .
-
Horizontal asymptote: To find the horizontal asymptote, we compare the degrees of the numerator and denominator. Since the degrees are the same (both are degree 1), the horizontal asymptote is found by dividing the leading coefficients: So, the horizontal asymptote is .
Summary for :
