domain of f(x)=x^4-2x^2-8

domain

f (x) = x^{4} - 2 x^{2} - 8

- \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 = arccos (3 - x)

f (x) = \frac{x ^{3} + x ^{2} - 2 x}{- 3 x ^{2} + 27}

11

f (x) = - 3 - 4 x - 12

\frac{1}{9 - x - 3}
