domain of f(x)=2x^2

domain

f (x) = 2 x^{2}

- \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{2}{x} - \frac{x}{x + 2}

f (x) = x 4 - x^{2}

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

f (x) = 15 - x

x^{3} - 64
