domain of sin(2x)

domain

sin (2 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

a sy m pt o t es \frac{2 x ^{2} - 6 x + 4}{x ^{2} - 5 x + 4}

d o main 2

in v erse f (x) = x^{2} + 6 x + 15

a sy m pt o t es f (x) = \frac{1 - 3 x}{2 - x}

e x t re m e f (x) = 7 x^{2} ln (\frac{x}{2})
