domain of f(x)=ln(ln|x|)

domain

f (x) = ln (ln ∣ x ∣)

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

- e^{x + 7}

f (x) = \frac{x - 1}{x - 3}

f (x) = \frac{3 x ^{2} - 2 x - 1}{x ^{2} + 3 x - 10}

sec (3 x)

f (x) = - \frac{7}{2 t t}

What is the domain of f(x)=ln(ln|x|) ?
The domain of f(x)=ln(ln|x|) is x<-1\lor x>1
