domain of f(x)=(x^2-4)/(x^2+6)

domain

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

- \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

\frac{2 x ^{2}}{ln ∣ x ∣ - 2}

f (x) = \frac{x + 2}{x ^{2} - 49 x}

x^{3} - 25 x

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