Question

the function $y = \frac{19,800}{x}$ is a rational function.
what is the domain of the function?
all real numbers except zero
all real numbers
all real numbers greater than zero

Explanation:

Step1: Recall domain of rational functions

For a rational function \( y = \frac{f(x)}{g(x)} \), the denominator \( g(x) \) cannot be zero (since division by zero is undefined).

Step2: Analyze the given function

The function is \( y=\frac{19800}{x} \). Here, the denominator is \( x \). So, we need to find all real numbers \( x \) such that \( x
eq0 \).

Answer:

all real numbers except zero
