1．The function f is given by $$\mathrm { f } ( x ) = \ln ( 2 x - 5 ) , \quad x > 2.5$$ （a）Find \(\mathrm { f } ^ { - 1 } ( x )\) ． The function g has domain \(x > 2\) and $$\operatorname { fg } ( x ) = \ln \left( \frac { x + 10 } { x - 2 } \right) , \quad x > 2$$ （b）Find \(\mathrm { g } ( x )\) and simplify your answer．
