domain of f(x)=ln(x^2-64)

domain

f (x) = ln (x^{2} - 64)

x < - 8 or x > 8

Interval Notation

(- \infty, - 8) \cup (8, \infty)

Solution steps

Find positive values for logs:

x < - 8 or x > 8

The function domain

x < - 8 or x > 8

\frac{1}{4} x^{2} + 1

f (x) = \frac{x ^{2} - 5 x - 6}{x ^{2} - 3 x - 4}

- ln (3 x + 9) - 7

\frac{2}{3} x + 2

\frac{x + 5}{x ^{2} + 4 x - 5}

What is the domain of f(x)=ln(x^2-64) ?
The domain of f(x)=ln(x^2-64) is x<-8\lor x>8
