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

domain

\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

\frac{2 m + 4}{8 m + m ^{2}}

\frac{x ^{2} - 4}{x - 3}

f (x) = \frac{( 1 - x )}{x}

\frac{6 x}{( x - 5 ) ( x - 9 )}

f (x) = 5^{x} - 3

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