Question 901601: Suppose f is a function that takes a real number x and performs the following three steps in the order given: (1) subtract 19; (2) square root; (3) make the quantity the denominator of a fraction with numerator 9. Find an expression for f(x). State the domain of f(x). (Enter your answer using interval notation.)
The argument for the square root cannot be negative, nor can the denominator expression be zero. Hence the square root argument must be strictly positive, i.e. .
As an interval, the domain is
