Consider the following functions.

Find the domain of

(Enter your answer using interval notation.)

Solution

(f/g)(x) = f(x)/g(x)

= [8/(x+9)]/[x/(x+9)]

= 8/x

(f/g)(x) = 8/x

domain of f(x) = R - {-9}

domain of g(x) = R - {-9}

domain of (f/g)(x) = R - {-9, 0}

Domain = (-infinity, -9) U (-9, 0) U (0, infinity)
