domain of f(x)=3+4/(x^2)

domain

f (x) = 3 + \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

2^{x} + 4

f (x) = - x^{2} + 3 x

5 x - 10

g (x) = e^{x^{2} - 3}

f (x) = 180000 - 30

What is the domain of f(x)=3+4/(x^2) ?
The domain of f(x)=3+4/(x^2) is x<0\lor x>0
