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

domain

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

f (x) = \frac{x + 1}{x - 3}

y = - 5 x + 3

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

f (x) = 9 cos (x) [0, 2 π]

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