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

domain

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

h (t) = - 16 t^{2} + 96 t + 168

\frac{1}{6 + x}

f (x) = \frac{- 13}{( x + 4 ) ^{2}}

f (x) = (\frac{x ^{2} - 9}{x + 3})
