domain of y=e^{-x}-1

domain

y = 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

y = - 1

\frac{x ^{2} + 8 x - 9}{x ^{2} + 3 x - 4}

f (x) = 3 ln (x) + 4

f (x) = - 4 x + 1

f (x) = 100 - 2 x
