domain of f(x)= 1/2 sqrt(4+x^2)

domain

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

- \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
