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

domain

f (x) = \frac{x}{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

f (x) = 8 - x^{2}

f (x) = \frac{7 x - 2}{x + 9}

f (x) = ∣ x ∣ - 3

4 x - x^{2} + 12

f (x) = \frac{x ^{2} + x}{x ^{2} - 7}

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