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

domain

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

\frac{4 - x ^{2}}{x ^{2}}

f (x) = x^{6} + x

2 x - 3 y = - 1

h (t) = 4 t^{2}

f (x) = 19 x^{4} - 114 x^{2}

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