domain of f(x)=ln(x^2-x-20)

domain

f (x) = ln (x^{2} - x - 20)

x < - 4 or x > 5

Interval Notation

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

Solution steps

Find positive values for logs:

x < - 4 or x > 5

The function domain

x < - 4 or x > 5

a sy m pt o t es f (x) = \frac{3 x ^{2} + 6}{x ^{2} - 2 x - 3}

in v erse f (x) = \frac{x + 2}{5 x - 1}

e x t re m e f (x) = x^{4} - 3 x^{2}

a sy m pt o t es f (x) = \frac{2 x + 8}{x ^{2} + 3 x - 4}

in v erse lo g_{10} (2 x + 5)
