domain of x^3+2x^2-5x-4

domain

x^{3} + 2 x^{2} - 5 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

x^{3} + 2 x^{2} - 5 x - 6

f (x) = 4 \cdot 3 x + 4

f (x) = \frac{1}{4} x + 40

f (x) = x^{4} - 8 x^{2} + 13
