domain of e^{-x}(x^2-1)

domain

e^{- x} (x^{2} - 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

f (x) = \frac{1}{4 x ^{2} - 5 x}

f (x) = 11 + 2 x

f (x) = \frac{( 9 x - 9 )}{( 2 x + 7 )}

f (x) = 10 x + 500

x^{4} - x^{3} - 6 x^{2}
