domain of f(x)=(2(x-9))/((x-18)x)

domain

f (x) = \frac{2 ( x - 9 )}{( x - 18 ) x}

x < 0 or 0 < x < 18 or x > 18

Interval Notation

(- \infty, 0) \cup (0, 18) \cup (18, \infty)

Solution steps

Find undefined (singularity) points:

x = 18, x = 0

The function domain

x < 0 or 0 < x < 18 or x > 18

x + 1 x - 1

f (x) = \frac{3 + x}{3 - x}

y = (\frac{1}{1 - x}) + 2 - x

f (x) = ((x^{2} + 2)^{2} + 5)

f (x) = \frac{7}{7 - x}

What is the domain of f(x)=(2(x-9))/((x-18)x) ?
The domain of f(x)=(2(x-9))/((x-18)x) is x<0\lor 0<x<18\lor x>18
