domain of y=e^{-x}-4

domain

y = e^{- x} - 4

- \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} - 4 x - 21

ln (arctan (x))

y = lo g_{10} (2 - 6 x)

f (x) = 2^{(x + 2)}

y = 4 x^{2} + 2 x - 5
