domain of f(x)=(|x|)/(x^2)

domain

f (x) = \frac{∣ x ∣}{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

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

f (x) = \frac{4 x ^{2} - 4}{x + 1}

f (x) = 6 x^{4} - 36 x^{2}

f (x) = \frac{x ( cos ( 4 x ) - x ^{3} )}{sin ( 2 x ) - 3}

y = 5 x - 13

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