domain of f(x)=(x^2-3)e^{-x}

domain

f (x) = (x^{2} - 3) 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

x x - 13 x

x^{2} - x + 2

f (x) = 2 x^{2} + x + 1

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

f (x) = 2 x^{2} + x + 6
