domain of (x^3)/(x^2-1)

domain

\frac{x ^{3}}{x ^{2} - 1}

x < - 1 or - 1 < x < 1 or x > 1

Interval Notation

(- \infty, - 1) \cup (- 1, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

x < - 1 or - 1 < x < 1 or x > 1

y = x^{\frac{9}{2}} - 6 x^{2}

f (x) = \frac{9 x}{x ( x ^{2} - 49 )}

- 1 + 2 sin (x + \frac{π}{3})

2 x - 1

f (x) = \frac{- 1 - 1 - 20 x}{10}
