domain of (x+7)/(x^2-16)

domain

\frac{x + 7}{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

(- 9, - 7), (- 3, 1)

3 x + 6

f (x) = \frac{4 x - 3}{x + 1}

3 x^{2} - 4

f (x) = - 1
