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

domain

f (x) = ln (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

(4, - 3), (- 2, - 3)

\frac{6}{7 + x}

- \frac{1}{4} x^{3}

(\frac{13}{3}, \frac{1}{7}), (\frac{1}{3}, \frac{8}{7})

y = \frac{1}{x ^{2} + 1}

What is the domain of f(x)=ln(x^2-4) ?
The domain of f(x)=ln(x^2-4) is x<-2\lor x>2
