domain of f(x)=4-2x^2

domain

f (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

f (x) = x^{4} - 6 x^{2}

f (x) = arccosh (x)

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

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

x (1 - x^{2})^{2}
