domain of f(x)=(2(x+2))/x

domain

f (x) = \frac{2 ( x + 2 )}{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

(8, 9), (4, - 3)

f (x) = 6 x^{5} - 4 x

f (x) = 6 x + 13

\frac{x ^{3}}{( x - 2 ) ^{2}}

f (x) = \frac{x}{5} + 1

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