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

domain

f (x) = \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) = x - 3 - 4

f (x) = lo g_{10} (4 - 2 x)

f (x) = lo g_{10} (16 x - x^{2})

f (x) = \frac{x - 5}{x + 8}

f (x) = - 2 x^{2} - 6 x + 11

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