domain of-2x^2+2x

domain

- 2 x^{2} + 2 x

- \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

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

\frac{x + 2}{x ^{2} - 3 x - 28}

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

f (x) = \frac{2}{( x ^{2} - 6 x + 8 )}

f (x) = \frac{9}{2 x + 1}
