domain of f(x)=(x+5)/(x+4)

domain

f (x) = \frac{x + 5}{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

\frac{x ^{2}}{x ^{2} - 1}

f (x) = 1 - \frac{( 4 + 3 x )}{5}

f (x) = \frac{8}{x} + 3

f (x) = x^{2} + 4 x - 1

f (x) = - x + 1 - 3

What is the domain of f(x)=(x+5)/(x+4) ?
The domain of f(x)=(x+5)/(x+4) is x<-4\lor x>-4
