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

domain

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

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

6 x - 24

f (x) = \frac{- 7}{2 t ^{\frac{3}{2}}}

x e^{- 8 x}

x^{2} - 4 x

f (x) = 5 x - 4

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