domain of f(x)= 5/(x^2)

domain

f (x) = \frac{5}{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

\frac{x + 7}{x - 5}

f (x) = 25 - x^{2} - 2

f (x) = ln (1 + x)

f (x) = \frac{x - 7}{4}

f (x) = \frac{x + 5}{x - 4}

What is the domain of f(x)= 5/(x^2) ?
The domain of f(x)= 5/(x^2) is x<0\lor x>0
