domain of f(x)=(x+4)/(2x)

domain

f (x) = \frac{x + 4}{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

y = x + 2

\frac{5 ( x ^{2} - 1 )}{x ^{2} - 4}

\frac{x ^{2} - 7}{x + 3}

f (x) = x^{2} - 6 x + 1

f (x) = 8 (x + 10)

What is the domain of f(x)=(x+4)/(2x) ?
The domain of f(x)=(x+4)/(2x) is x<0\lor x>0
