domain of-x^4+x^3+9x

domain

- x^{4} + x^{3} + 9 x

- \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) = arcsin (2 x)

f (x) = x^{5} + x

f (x) = \frac{1}{3} x^{3} - 2 x^{2} + 3 x

(1, 1), (2, 2)

y = \frac{1}{2} ∣ x + 4 ∣
