domain of (x^2+3x-4)/(x+4)

domain

\frac{x ^{2} + 3 x - 4}{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) = \frac{4 x + 3}{9 + 4 x}

\frac{x - 1}{1 + x ^{2}}

f (x) = \frac{- 12}{x ^{2} + 8 x + 12}

f (x) = \frac{1}{( x - 5 ) ^{2}}

4 x + 10 y = - 20
