domain of y=x^3+2x^2

domain

y = x^{3} + 2 x^{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 ^{3} + 1}{x ^{2} - 1}

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

\frac{4}{2 x - 3}

f (x) = sin (6 x)

f (X) = X^{2} - 4
