domain of (x^2-1)/(x^2+1)

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

f (x) = - 2 cos (3 x - \frac{π}{2})

f (x) = 6 x - 9

f (x) = lo g_{10} (x - 7)

\frac{4}{5} x

lo g_{2} (2 x - 5) - lo g_{2} (x + 3)

What is the domain of (x^2-1)/(x^2+1) ?
The domain of (x^2-1)/(x^2+1) is -infinity <x<infinity
