domain of f(x)=|x^2-1|

domain

f (x) = x^{2} - 1

- \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 - 3}{x + 4}

\frac{x + 2}{11 - x}

f (x) = 6 lo g_{2} (x - 8) - 6

\frac{x ^{2} - 1}{x - 8}

y = (5 x + 5)^{2}
