domain of (x^2-16)/(x+4)

domain

\frac{x ^{2} - 16}{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

sy mm e t ry y^{2} - 4 y - 6 x - 5 = 0

in v erse f (x) = \frac{3}{x ^{2} + 2 x}

a sy m pt o t es f (x) = \frac{x ^{2} + 9 x + 8}{x - 1}

y = \frac{1}{x ^{2}}

d o main \frac{3}{x + 2} + \frac{x}{x + 2}

What is the domain of (x^2-16)/(x+4) ?
The domain of (x^2-16)/(x+4) is x<-4\lor x>-4
