domain of f(x)=|x^2-4|

domain

f (x) = 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

f (x) = x^{3} - 9 x^{2} + 27 x - 25

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

y = lo g_{4} (x + 1)

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