domain of y=e^x-2e^{-x}-3x

domain

y = e^{x} - 2 e^{- x} - 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

f (x) = ∣ x + 2 ∣ - ∣ x - 2 ∣ + 2 x - 1

f (x) = cos^{2} (\frac{x}{1800})

y = (1 + x)^{2}

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

f (x) = 40 x^{2} - 69 x - 6

What is the domain of y=e^x-2e^{-x}-3x ?
The domain of y=e^x-2e^{-x}-3x is -infinity <x<infinity
