domain of log_{10}(x^2-4)

domain

lo g_{10} (x^{2} - 4)

x < - 2 or x > 2

Interval Notation

(- \infty, - 2) \cup (2, \infty)

Solution steps

Find positive values for logs:

x < - 2 or x > 2

The function domain

x < - 2 or x > 2

- \frac{1}{x ^{2} + 6 x - 7}

\frac{2}{3} x - 4

f (x) = \frac{2 x + 3}{x - 5}

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

f (x) = - x - 3

What is the domain of log_{10}(x^2-4) ?
The domain of log_{10}(x^2-4) is x<-2\lor x>2
