There are three real numbers that are not in the domain of f(x) = (x - 1)(x - 2)(x - 3)/(x(x - 1)(x - 2)) What is the sum of those three numbers?
The domain of\(f(x) = (x - 1)(x - 2)(x - 3)/(x(x - 1)(x - 2) \)
is
\(x\in \mathbb R \ |\ x \in \{0,1,2\}\\ \color{blue}0+1+2=3\)
The sum of those three numbers is 3.
