domain of (8x-24)/(x^2-x-20)

domain

\frac{8 x - 24}{x ^{2} - x - 20}

x < - 4 or - 4 < x < 5 or x > 5

Interval Notation

(- \infty, - 4) \cup (- 4, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 4

The function domain

x < - 4 or - 4 < x < 5 or x > 5

\frac{x ^{2} - 9}{x ^{2} - 16}

g (x) = \frac{5}{3 x - 1}

f (x) = \frac{x ^{2} + 4}{x ^{2} - 1}

f (x) = x^{4} - 2 x^{2} - 8

y = arccos (3 - x)
