domain of f(x)= 1/2 sin(2x)-cos(x)

domain

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

\frac{1}{\frac{5}{- 8 x - 10} + 2}

f (x) = \frac{x - 3}{x ^{2} - 2 x - 15}

\frac{2}{3} x^{3} + 2 x^{2} + 6 x - 5

f (x) = tan (2 x + 1)

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