domain of (2-x)e^{-x}-1

domain

(2 - x) e^{- x} - 1

- \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 + 4 y = 0

y = - 2 x + 6 y

y = 4 x - 8

f (x) = - 5 x^{2}

f (x) = - \frac{1}{3} x + 1
