domain of f(x)=x^4-5x^2-1

domain

f (x) = x^{4} - 5 x^{2} - 1

- \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 - [x]]

f (x) = 2^{x + 2} - 3

f (x) = \frac{( - 4 x - 3 )}{( x - 2 )}

f (x) = x^{4} - 5 x^{2} + 4

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