domain of f(x)=(x+11)/(x^2-121)

domain

f (x) = \frac{x + 11}{x ^{2} - 121}

x < - 11 or - 11 < x < 11 or x > 11

Interval Notation

(- \infty, - 11) \cup (- 11, 11) \cup (11, \infty)

Solution steps

Find undefined (singularity) points:

x = 11, x = - 11

The function domain

x < - 11 or - 11 < x < 11 or x > 11

What is the domain of f(x)=(x+11)/(x^2-121) ?
The domain of f(x)=(x+11)/(x^2-121) is x<-11\lor-11<x<11\lor x>11
