domain of f(x)=(9(x+11))/(11x)

domain

f (x) = \frac{9 ( x + 11 )}{11 x}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

f (x) = \frac{x}{x ^{2} + 6 x + 8}

x^{2} - x - 6

f (x) = \frac{2}{x - 1}

x - x

1 0^{x - 2} - 5

What is the domain of f(x)=(9(x+11))/(11x) ?
The domain of f(x)=(9(x+11))/(11x) is x<0\lor x>0
