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

domain

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

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

∣ x - 2 ∣

f (x) = x^{3} + 5

y = 5 cos (2 x + \frac{π}{2})

(0, - 2), (2, 6)
