domain of x^4+2x^2

domain

x^{4} + 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

y = lo g_{b} (x)

\frac{1}{x} + \frac{3}{5 x}

x = t^{2}

f (x) = \frac{1}{x ^{2} + 4}

y = \frac{x ^{2} - x + 6}{x - 2}
