Math Problem Statement
Solution
The given function is:
Let's go through the steps to solve the problem:
1. Domain:
The domain consists of all real numbers except where the denominator equals zero (since division by zero is undefined).
Set the denominator equal to zero and solve:
So, the domain is:
2. X-intercept:
The x-intercept occurs when , which means the numerator of the function equals zero.
Set and solve:
Thus, the x-intercept is at .
3. Y-intercept:
The y-intercept occurs when .
Substitute into the function:
Thus, the y-intercept is at .
4. Asymptotes:
-
Vertical Asymptote: The vertical asymptote occurs where the denominator equals zero, which we've already found to be at .
-
Horizontal Asymptote:
