domain of f(x)=x^3+4x^2

domain

f (x) = x^{3} + 4 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}{x}

\frac{x}{x ^{2} + 1}

\frac{3 - 3 x}{3 x + 4}

m = - \frac{2}{3}, (- 5, - 3)

x - x^{2}
