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

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

What is the domain of f(x)= x/(sqrt(x^2+4)) ?
The domain of f(x)= x/(sqrt(x^2+4)) is -infinity <x<infinity
