domain of f(x)= 1/(x^2+2)+x^3cos(x)

domain

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

- \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^{2} - 250 x + 3300

f (x) = cos (\frac{4 x}{3})

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

f (x) = 3 lo g_{2} (- x) - 9

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

What is the domain of f(x)= 1/(x^2+2)+x^3cos(x) ?
The domain of f(x)= 1/(x^2+2)+x^3cos(x) is -infinity <x<infinity
