Question

Determine the domain of the function. (5 points) Please state whether A,B,C or D

Answer 1

Answer:

Option C is correct.

All real numbers except 9

Step-by-step explanation:

Given the function: $f(x) = \frac{x}{x-9}$

To find the domain of the function:

Domain of a function is the set of all the possible values of the independent variable.

Since, the given function is a rational function and the denominator cannot equal zero because it would be undefined.

therefore, the domain of the function f(x)is, all real numbers except 9
