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

domain

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

x < - 1 or - 1 < x < 4 or x > 4

Interval Notation

(- \infty, - 1) \cup (- 1, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 1

The function domain

x < - 1 or - 1 < x < 4 or x > 4

f (x) = ln (x) + 3

p (x) = 2 x^{2} + 3 x

f (x) = \frac{x - 5}{x + 6}

\frac{( x - 2 )}{( x + 3 ) 1 - x}

f (x) = x - 3 x^{\frac{1}{3}}
