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

domain

f (x) = \frac{( 2 + x )}{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 + 3}{x}

x^{3} + 5

f (x) = 2 - 2 x^{2}

f (x) = x^{2} + 3 x + 2

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

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