domain of x/(x^2+13x+36)

domain

\frac{x}{x ^{2} + 13 x + 36}

x < - 9 or - 9 < x < - 4 or x > - 4

Interval Notation

(- \infty, - 9) \cup (- 9, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4, x = - 9

The function domain

x < - 9 or - 9 < x < - 4 or x > - 4

\frac{7 + 5 x}{3 x - 5}

2 tan (2 x) + 1

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

f (x) = \frac{10}{x ^{2} + 4}

f (x) = \frac{x ^{2} + x - 20}{x ^{2} - 14 x + 48}
