domain of f(x)=(x-1)/(x+4)

domain

f (x) = \frac{x - 1}{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{5 x - 2}{7 x + 3}

4 cos (x) sin (x) - 4 sin (x)

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

f (x) = - 4 x - 3

x + 1

What is the domain of f(x)=(x-1)/(x+4) ?
The domain of f(x)=(x-1)/(x+4) is x<-4\lor x>-4
