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

domain

f (x) = 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) = \frac{5 x}{14 - x}

4 x + 2

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

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

5 - 2 x
