domain of (x-1)/(x^4-3x^2-4)

domain

\frac{x - 1}{x ^{4} - 3 x ^{2} - 4}

x < - 2 or - 2 < x < 2 or x > 2

Interval Notation

(- \infty, - 2) \cup (- 2, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

x < - 2 or - 2 < x < 2 or x > 2

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

f (x) = \frac{1000 + 600 x}{10 + 0.6 x}

\frac{1}{x ^{2} - 3 x}

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