domain of f(x)=(1-x)e^x

domain

f (x) = (1 - x) 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

y = \frac{9 x}{x ^{2} + 4 x - 5}

f (x) = \frac{3 x}{8}

f (x) = 5 x^{4} - 30 x^{2}

y = \frac{5 x - 2}{3 + 2 x}

e^{x} cos (x)
