domain of f(x)=3x^3-2

domain

f (x) = 3 x^{3} - 2

- \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} + x - 6}{x ^{2} - 4}

\frac{x}{x ^{2} + 10 x + 24}

y = - 2 x + 8

f (x) = 2 x^{2} + 8 x + 2

f (x) = \frac{x - 5}{x - 11}
