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

domain

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

x \leq - 1 or x \geq 3

Interval Notation

(- \infty, - 1] \cup [3, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 1 or x \geq 3

The function domain

x \leq - 1 or x \geq 3

f (x) = - 4 x

f (x) = 2 - ln (- x + 3)

(2, - 9), (- 7, 8)

(9.5) (- 1.9)

f (x) = 1650 (1.022)^{t}

What is the domain of f(x)=sqrt(ln(x^2-2x-2)) ?
The domain of f(x)=sqrt(ln(x^2-2x-2)) is x<=-1\lor x>= 3
