domain of 9/(x^2+2x)

Solution

domain

\frac{9}{x ^{2} + 2 x}

Solution

x < - 2 or - 2 < x < 0 or x > 0

+1

Interval Notation

(- \infty, - 2) \cup (- 2, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 2

The function domain

x < - 2 or - 2 < x < 0 or x > 0

Popular Examples

extreme f(x)=2x^3+6x^2-18x extreme points

f (x) = 2 x^{3} + 6 x^{2} - 18 x

parity cos(x^2)+5cot(x)parity

cos (x^{2}) + 5 cot (x)

intercepts of f(x)=(6x^2)/(x^2-4)intercepts

f (x) = \frac{6 x ^{2}}{x ^{2} - 4}

domain of f(x)=(x-3)/(x^2-4x-12)domain

f (x) = \frac{x - 3}{x ^{2} - 4 x - 12}

symmetry x^2-4x+3 symmetry

x^{2} - 4 x + 3
