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

domain

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

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

\frac{x ^{3} + 8}{x ^{2} - 8}

3 x + 2 y = 2

f (x) = - 5 x + 8 y = 14

f (x) = x^{2} e^{x} - 7

f (x) = \frac{2 x - 7}{x ^{2} - 5 x + 6}

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