domain of f(x)=(x^2+5)/(x^2+81)

domain

f (x) = \frac{x ^{2} + 5}{x ^{2} + 81}

- \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

g (x) = - 3 x + 12

5 x + 25

f (x) = \frac{1}{4 x + 7}

f (t) = 16 - t^{2}
