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

domain

f (x) = \frac{2 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

(\frac{5}{6})^{\frac{x ^{2} - 3 x}{x ^{2}}}

lo g_{10} (5 - 2 x)

\frac{2}{x ^{2} - 1} + x + 3

\frac{1}{2} tan (2 x)

f (x) = - x + 1

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