To find the domain of the function $$ f(x) = \sqrt{2x - 18} $$, we need to ensure that the expression inside the square root is non-negative (since the square root of a negative number is not defined in the set of real numbers).

1. **Set the inside of the square root greater than or equal to zero:**
   $$
   2x - 18 \geq 0
   $$

2. **Solve for $$ x $$:**
   $$
   2x \geq 18
   $$
   $$
   x \geq 9
   $$

Therefore, the domain of the function is all real numbers $$ x $$ such that $$ x $$ is greater than or equal to 9.

**The domain is** $$[9, \infty)$$.

**Answer:** $$[9, \infty)$$
The domain is $$[9, \infty)$$.
