domain of f(x)=((x^2-4))/x

domain

f (x) = \frac{( x ^{2} - 4 )}{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

csc (- 2 x)

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

f (x) = tan (\frac{1}{2} x + π) + 1

f (x) = e^{5 x}

f (x) = 7 x + 9

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