domain of ln(x^2+x-20)

Solution

domain

ln (x^{2} + x - 20)

Solution

x < - 5 or x > 4

+1

Interval Notation

(- \infty, - 5) \cup (4, \infty)

Solution steps

Find positive values for logs:

x < - 5 or x > 4

The function domain

x < - 5 or x > 4

Popular Examples

domain of f(x)=(x^2+5x+6)/(x^2+2x-8)domain

f (x) = \frac{x ^{2} + 5 x + 6}{x ^{2} + 2 x - 8}

domain of f(x)= 1/(x+5)-1/(x-5)=0 domain

f (x) = \frac{1}{x + 5} - \frac{1}{x - 5} = 0

domain of 5/(\frac{11){x}+2}domain

\frac{5}{\frac{11}{x} + 2}

domain of x^3-3x^2+7x+1 domain

x^{3} - 3 x^{2} + 7 x + 1

domain of f(x)=-4/(1+x^2)domain

f (x) = - \frac{4}{1 + x ^{2}}
