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

domain

f (x) = x^{4} + 3 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{3 x ^{3} + 2 x + 2}{2 x ^{3} + 5 x - 5}

y = x^{2} + 3 x - 4

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

f (x) = - 4 (x + 3) (x + 7)

(1, - 1), (5, 2)
