The domain of the function are the possible "x" values the equation can take.
Since the function is f(x) = (x + 5)/(x - 2), the domain must not be x = 2 because it will make the denominator zero and thus, the function becomes undefined.
Therefore, the domain of this function are all real numbers except 2.
In interval notation, the domain is (-∞, 2) ⋃ (2, ∞).
