domain of x^4+2x^2+2

domain

x^{4} + 2 x^{2} + 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

y = x

y = - \frac{2}{5} x + 2

f (x) = \frac{( \frac{7}{x} )}{( x - 3 )}

\frac{6 x}{x - 7}

f (x) = \frac{2}{3}
