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

domain

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

x < - 6 or x > 3

Interval Notation

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

Solution steps

Find positive values for logs:

x < - 6 or x > 3

The function domain

x < - 6 or x > 3

- 3 x^{3} + 10 x^{2} - 13 x + 11

\frac{2 x}{5 x - 9}

6 - ∣ x ∣

\frac{1}{( x ( 3 - x ^{2} ) )}

f (x) = \frac{( \frac{x}{x - 7} )}{( \frac{x}{x + 7} )}

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