domain of (x^2-1)/(x^3+9x^2+14x)

domain

\frac{x ^{2} - 1}{x ^{3} + 9 x ^{2} + 14 x}

x < - 7 or - 7 < x < - 2 or - 2 < x < 0 or x > 0

Solution steps

Find undefined (singularity) points:

x = 0, x = - 2, x = - 7

The function domain

x < - 7 or - 7 < x < - 2 or - 2 < x < 0 or x > 0

f (x) = x^{2} - 6 x

f (x) = \frac{2}{3} x + 7

f (x) = \frac{4 x - 1}{2 x + 3}

3 sin (\frac{1}{4} x - \frac{5}{3} π) - 3
