domain of x^3+3x^2+2x-1

domain

x^{3} + 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

(- \frac{1}{2}, \frac{3}{2}), (- \frac{15}{2}, - \frac{7}{2})

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

f (x) = x^{2} + 2 x + 2

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

f (x) = - x + 6
