domain of f(x)= 6/(x^2+1)

domain

f (x) = \frac{6}{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) = \frac{2}{( 3 x ) - 4}

x^{\frac{1}{5}}

\frac{x ^{2} + 12 x + 32}{x ^{2} - 2 x - 15}

f (x) = \frac{x ^{3} - 1}{x + 3}

5 x - 15
