domain of f(x)=8+2/(x^2)

domain

f (x) = 8 + \frac{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) = 6 - \frac{1}{4} x

(7, 3), (1, - 1)

f (x) = 5 x^{4} - 8

f (x) = 4 - 2 x

(0.2, - 0.5), (100, 10)

What is the domain of f(x)=8+2/(x^2) ?
The domain of f(x)=8+2/(x^2) is x<0\lor x>0
