domain of f(x)=(x^2+4x+4)e^{-2x}

domain

f (x) = (x^{2} + 4 x + 4) e^{- 2 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} + 5 x - 6

f (x) = 8 - 2 x + 1

g (x) = lo g_{3} (x - 3) - 1

\frac{900 - 100 x ^{2}}{9}
