Given the below problem, the two equations can't simplified further. So to find the domain, you need to look for the domain where they're both valid, eg $[-2, 5]$.
|
||
|
|
$$ \sqrt{x+2} + \sqrt{5-x} $$
|
||
|
|
The below example has a domain of $[-2, 5)$ because $x$ cannot equal 0 for the denominator
|
||
|
|
$$ \frac{\sqrt{x+2}}{\sqrt{5-x}} $$

Assuming $f(x) = \frac{2}{x-3}$,
