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

domain

\frac{x ^{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

y = x^{2} - 5

f (x) = \frac{1}{x ^{3} - x ^{2} - 6 x}

x^{2} + 3 x - 4

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

7 x + 5 y = 4

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