domain of f(x)=(x+3)/(x+4)

domain

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

16 - 2 x - x^{2}

e^{- 7 x}

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

f (x) = \frac{2 ( x + 6 )}{3 x}

h (x) = \frac{x}{2} + \frac{2}{x}

What is the domain of f(x)=(x+3)/(x+4) ?
The domain of f(x)=(x+3)/(x+4) is x<-4\lor x>-4
