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

domain

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

- \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 (t) = t + 7

\frac{1}{x ^{2} - 4}

(x^{3} - x - 18)^{4}

y = - 4 x^{2} + 8 x

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