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

domain

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

f (x) = \frac{5 x ^{2}}{3 + x}

\frac{4}{5}

f (x) = \frac{x ^{2} + 3}{7 x - 4 x ^{2}}

f (x) = 4 x - 6

3 x^{4} + 16 x^{3}

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