domain of f(x)=4^{x-1}

domain

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

f (x) = x^{2} + 4 x - 1, x \geq - 2 - 5

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

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

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