domain of log_{2}(x^2-1)

domain

lo g_{2} (x^{2} - 1)

x < - 1 or x > 1

Interval Notation

(- \infty, - 1) \cup (1, \infty)

Solution steps

Find positive values for logs:

x < - 1 or x > 1

The function domain

x < - 1 or x > 1

ln (2 t - 1)

\frac{3 x - 1}{2 x + 3}

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

f (x) = 3^{x} - 3

f (x) = 3^{x} - 4
