domain of f(x)=ln(x^2-3x-18)

domain

f (x) = ln (x^{2} - 3 x - 18)

x < - 3 or x > 6

Interval Notation

(- \infty, - 3) \cup (6, \infty)

Solution steps

Find positive values for logs:

x < - 3 or x > 6

The function domain

x < - 3 or x > 6

f (x) = 4 e^{5 x + 1}

x + 5

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

\frac{8 x + 9}{x + 8}

\frac{1}{4} x^{4} - \frac{1}{3} x^{3} - 3 x^{2}

What is the domain of f(x)=ln(x^2-3x-18) ?
The domain of f(x)=ln(x^2-3x-18) is x<-3\lor x>6
