what is the domain of the following function? (write your answer in internal notation.)
f(x) = (square root(x-3))/(ln(2x-27)).
~~~~~~~~~~~~~~~~~~~~~~~~~ 

The domain in this case is the solution of two inequalities:


(1)  x >= 3,         and
(2)  2x - 27 > 0.


Thus it is the set (27%2F2,infinity%29), or, which is the same, (13.5,infinity).
