domain of f(x)=(1/2)^x

domain

f (x) = (\frac{1}{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) = ln (- 3 x + x^{2})

3 x + 2 y = - 4

f (x) = \frac{x ^{7}}{3} + 4

y = x^{2} + 4 x - 5

f (x) = \frac{( e ^{x} - e ^{- x} )}{2}
