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

domain

\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

x^{\frac{1}{9}} + 2

f (x) = x^{2} - 4 x + 10

x^{2} - \frac{3}{5}

\frac{x ^{2} + 3 x - 28}{x ^{2} - 16}

3^{x - 5}

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