 The below example has a domain of $[-2, 5)$ because $x$ cannot equal 0 for the denominator

+Assuming $f(x) = \frac{2}{x-3}$, and $g(x) = \frac{5}{x+1}$, $(f\circ g)(x)$, you can find the domain by finding the domain for each function, then fully expanding it and seeing if any more unreachable numbers are included
