domain of f(x)=(x^2+1)/(x^2+5)

domain

f (x) = \frac{x ^{2} + 1}{x ^{2} + 5}

- \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

y = x^{2} + 8

y = \frac{6 + x}{3 - x}

f (x) = 3 x + \frac{5}{4}

f (x) = \frac{x + 3}{x + 2}

\frac{- 11 x + 1}{- 30 x ^{2} - 25 x + 5}
