domain of f(x)=(x^2-1)/(x^2+4)

domain

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

- \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

arcsin (3 x + 1)

f (x) = - (x - 2)^{2}

f (x) = 1 + sin (x)

g (x) = 25 - x^{2}

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