domain of ln(x^2-18x)

Solution

domain

ln (x^{2} - 18 x)

Solution

x < 0 or x > 18

+1

Interval Notation

(- \infty, 0) \cup (18, \infty)

Solution steps

Find positive values for logs:

x < 0 or x > 18

The function domain

x < 0 or x > 18

Popular Examples

extreme f(x)=x+2/x extreme points

f (x) = x + \frac{2}{x}

critical ((x^2-9))/(x^3+3x^2)critical points

\frac{( x ^{2} - 9 )}{x ^{3} + 3 x ^{2}}

inverse of f(x)=(-x-2)/(x+4)inverse

f (x) = \frac{- x - 2}{x + 4}

extreme f(x)=0.002x^3+5x+6.244 extreme points

f (x) = 0.002 x^{3} + 5 x + 6.244

domain of f(x)=-5x-4 domain

f (x) = - 5 x - 4
