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

domain

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

- x + 7

f (x) = - 1 + 3 cos (\frac{3}{2} x)

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

f (x) = 8 x - 5

f (x) = \frac{4}{- x + 1} + 2
