domain of f(x)=2x^3-x^2+2x-1

domain

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

- \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) = 4 x^{3} - 5 x^{2} + 2 x - 1

3 x - 8

f (x) = x^{3} - 10 x^{2} + 29 x - 20

y - 3 x = 1

y = 2
