domain of (x^2+9x+20)/(x+4)

domain

\frac{x ^{2} + 9 x + 20}{x + 4}

x < - 4 or x > - 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

y = x + \frac{3600}{x}

\frac{\frac{4}{x}}{\frac{4}{x} + 4}

f (x) = \frac{3}{( x - 1 ) ( x ^{2} - 4 )}

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

\frac{2}{3 x + 9}

What is the domain of (x^2+9x+20)/(x+4) ?
The domain of (x^2+9x+20)/(x+4) is x<-4\lor x>-4
