Answer 2

I can help you with math problems, among other things. To find the domain of a function, you need to determine the values of x that make the function undefined. For the function $$f(x) = \frac{x-1}{x+2}$$, the function is undefined when the denominator is zero, which happens when $$x = -2$$. Therefore, the domain of the function is all real numbers except $$-2$$. You can write it as $$(-\infty, -2) \cup (-2, \infty)$$ or $$\{x \in \mathbb{R} | x \neq -2\}$$. If you need more help, you can check out this [video] that explains how to find the domain of rational functions.
