domain of f(x)=ln(x^2-5)

domain

f (x) = ln (x^{2} - 5)

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) = e^{- x} + 4

f (x) = \frac{3 e ^{x}}{e ^{x} - 2}

f (x) = 2 sin (2 x)

f (x) = x^{2} - 20 x + 104

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