domain of f(x)=ln(x^2-25)

domain

f (x) = ln (x^{2} - 25)

x < - 5 or x > 5

Interval Notation

(- \infty, - 5) \cup (5, \infty)

Solution steps

Find positive values for logs:

x < - 5 or x > 5

The function domain

x < - 5 or x > 5

f (x) = 4

\frac{5 x + 1}{5 x - 20} + \frac{x + 17}{20 - 5 x}

\frac{5 x}{3} + 12

f (x) = e^{x} + 4

f (x) = [x]

What is the domain of f(x)=ln(x^2-25) ?
The domain of f(x)=ln(x^2-25) is x<-5\lor x>5
