domain of (x-2)/(x+4)

domain

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

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = - 7 x + 7

f (x) = - 5 x + 3

csc (\frac{( x \cdot π )}{2}) + 1

f (x) = \frac{- 5 x - 10}{x ^{2} + 2 x}

\frac{x - 5}{x ^{2} - 25}
