domain of f(x)=2sin(2x)

domain

f (x) = 2 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

f (x) = x^{2} - 20 x + 104

f (x) = \frac{2 x + 2}{x ^{2} + 3 x - 40}

y = ∣ x + 3 ∣

y = 2^{x} + 1

f (x) = ln (5 x + 3)
