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

domain

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

x < - 1 or - 1 < x < 3 or x > 3

Interval Notation

(- \infty, - 1) \cup (- 1, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = - 1

The function domain

x < - 1 or - 1 < x < 3 or x > 3

\frac{2 x + 7}{x + 2}

f (x) = \frac{5}{x - 4} + x^{2} - 9

f (x) = x^{2} - 4, x \leq - 2

\frac{4 - s ^{2}}{2 s ^{2} - 7 s - 4}

y = \frac{x}{2 ( 2 + x )}
