domain of f(x)= 4/(x^2)

domain

f (x) = \frac{4}{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) = x^{2} - 2 x + 1

f (x) = \frac{2 x ^{2} + 8 x + 8}{x ^{3} + 8}

f

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

f (x) = ln (2 x - 1)

What is the domain of f(x)= 4/(x^2) ?
The domain of f(x)= 4/(x^2) is x<0\lor x>0
