domain of f(x)= 7/(x^2)

domain

f (x) = \frac{7}{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

2 x - 12

2 x - 16

f (x) = 4 x^{2} + 5

f (x) = x - 2 - 2

f (x) = x - 2 + 2

What is the domain of f(x)= 7/(x^2) ?
The domain of f(x)= 7/(x^2) is x<0\lor x>0
