domain of (x+4)/(x^2-16)

domain

\frac{x + 4}{x ^{2} - 16}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

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

f (x) = - x^{2} + 10 x - 16 - 3

f (x) = lo g_{7} (x - 7)

f (x) = x + 5 + 3 - 2 x

f (x) = x^{2} - 8 x + 7

\frac{( x ^{2} + x )}{2}
