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

domain

f (x) = \frac{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

f (x) = f (x)^{1} (x) = x

ln (\frac{x}{x + 3})

f (x) = \frac{7 x}{x ^{2} - 9}

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