domain of f(x)=(x^2-19x-20)/(x+5)

domain

f (x) = \frac{x ^{2} - 19 x - 20}{x + 5}

x < - 5 or x > - 5

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

f (x) = \frac{1}{x - 3} + 5

- 1 + 2 - x^{2}

\frac{8}{1 - \frac{1}{z}} - \frac{9}{1 - 0.5 \frac{1}{z}} + 2

f (x) = - 3 ∣ x ∣

f (x) = \frac{- 10}{x ^{2} - x - 20}

What is the domain of f(x)=(x^2-19x-20)/(x+5) ?
The domain of f(x)=(x^2-19x-20)/(x+5) is x<-5\lor x>-5
