domain of f(x)=(x-2)/(x+1)

domain

f (x) = \frac{x - 2}{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

2 x^{2} - 3 x + 1

- 2 x + 8 y = 5

2 x^{3} + 18 x^{2} + 30 x + 2

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

- x^{2} - 4 x + 4

What is the domain of f(x)=(x-2)/(x+1) ?
The domain of f(x)=(x-2)/(x+1) is x<-1\lor x>-1
