Question

find the domain of f(x)=x/(x-3)

Answer 1

\[f(x) = \frac{x}{x - 3}\]

Basically you can assume the domain of a given function is all real numbers unless you can find a number or set of numbers that cannot be part of the domain. Do you see a number or set of numbers that do not belong to the domain?

Answer 2

well 3 cant be x because it would make the denominator 0.. right?

Answer 3

Correct
