<font face="Times New Roman" size="+2">


Do you mean


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x\ -\ 9\sqrt{x}\ +\ 18]


or


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x\ -\ 9\sqrt{x\ +\ 18}]


Use parentheses when you re-post.  Also, provide the answer you got so that we have a better idea of what your particular difficulty is.
