domain of y=tanh(3x)

domain

y = tanh (3 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

- x^{2} + 2 x + 3

(x - 2)^{\frac{1}{2}}

f (x) = 12 - 4 x

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

- 2^{- x} + 6
