domain of log_{10}(x^2-1)

domain

lo g_{10} (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

f (x) = \frac{x + 9}{x ^{2} - 9}

f (x) = \frac{7 x + 3}{x}

3 x - y = 7

- \frac{1}{5}
