domain of y=(2x^3)/(x^2+1)

domain

y = \frac{2 x ^{3}}{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

x^{2} - 6 x + 14

- \frac{x}{4 - x ^{2}}

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

y = x - 9 + 7

\frac{1}{( \frac{1}{x ^{2}} ) ^{2}}
