Final Answer:
The domain of the function f(x) = 7/(x-2) is all real numbers except x ≠ 2.
Step-by-step explanation:
The domain of a function represents the set of valid input values for which the function is defined. In the case of the function
the denominator
must not equal zero to avoid division by zero, as this operation is undefined in mathematics.
Setting
equal to zero and solving for x, we find that
makes the denominator zero. Consequently, the function is undefined at
. Therefore, the domain of the function excludes
, and we express this as
where
denotes the set of all real numbers, excluding

This restriction ensures that the function is well-defined for all other real values of x, emphasizing the importance of avoiding situations where the denominator becomes zero to maintain mathematical coherence and validity.
