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

x - 4

\frac{e ^{x - 1}}{x}

h (x) = 4 - x^{2}

f (t) = \frac{1}{t + 1}

2 tan (\frac{x}{2})
