domain of f(x)= x/(x^2+11x+28)

domain

f (x) = \frac{x}{x ^{2} + 11 x + 28}

x < - 7 or - 7 < x < - 4 or x > - 4

Interval Notation

(- \infty, - 7) \cup (- 7, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4, x = - 7

The function domain

x < - 7 or - 7 < x < - 4 or x > - 4
