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

domain

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

\frac{1}{1 + e ^{x}}

lo g_{6} (2 x - 4)

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

f (x) = 8 x^{2} - 77 x + 45
