domain of f(x)=sqrt(9+x^2)

domain

f (x) = 9 + 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

arcsin (\frac{1}{1 - x})

\frac{t - 2}{4 t - 12}

f (x) = \frac{5 x + 2}{x - 5}

f (x) = x^{2} - x - 12

y = \frac{2 x + 5}{9 x - 8}

What is the domain of f(x)=sqrt(9+x^2) ?
The domain of f(x)=sqrt(9+x^2) is -infinity <x<infinity
