Question 697269
You are correct. So the domain in set-builder notation would be


<img src="http://latex.codecogs.com/gif.latex?\large \{x|x\in \mathbb{R},x \neq 2, x \neq 3\}" title="X" />


This basically says "x can be any real number BUT it cannot be 2 and it cannot be 3"


In interval notation, the domain is <img src="http://latex.codecogs.com/gif.latex?\large (-\infty,2)\cup(2,3)\cup(3,\infty)" title="X" />


This says the same thing more or less but now we're talking about the interval  <img src="http://latex.codecogs.com/gif.latex?\large (-\infty,\infty)" title="X" />, but we're "poking" holes in this interval at x = 2 and x = 3 when we write what's above.
