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

domain

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

\frac{2}{8 - x ^{3}}

f (x) = 11 (\frac{1}{3})^{x}

f (x) = \frac{x - 5}{x - 3 - 3}

f (x) = \frac{15}{x + 2}
