domain of sin(x^3)

domain

sin (x^{3})

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = \frac{x ^{2} + 4}{x ^{2} - 2 x - 8}

f (x) = - 0.5 sec (\frac{π}{2} x + \frac{π}{3})

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

x + 5 + 2

x + 5 + 4
