domain of (x+4)/(x^2-25)

domain

\frac{x + 4}{x ^{2} - 25}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

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

f (x) = (x - 3)^{2} - 4

f (x) = - 2 cos (3 x)

f (x) = \frac{x ^{2} + 7 x + 8}{x + 3}

f (x) = cos (\frac{23 π}{6})

6 y - 3 x = - 24
