domain of f(x)=(sqrt(x-1))/(sqrt(x+1))

domain

f (x) = \frac{x - 1}{x + 1}

x \geq 1

Interval Notation

[1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 1

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

x \geq 1

f (x) = \frac{13}{3 x + 13}

f (x) = x^{2} + 8 x - 20

f (x) = \frac{1}{ln ( x + 1 )}

- (\frac{1}{4})^{x} - 2

\frac{- 2 x ^{2} + 5 x - 1}{2 x - 1}
