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

domain

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

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

\frac{x ^{2} - 3 x - 4}{x + 2}

- x^{2} + 9

- 10 (x + 9)^{4} (x - 4)^{4}

f (x) = \frac{9 x}{2 x - 1}

f (x) = (x^{2} - 9) + 5

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