domain of f(x)=-4^x

domain

f (x) = - 4^{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

\frac{3}{x ^{2} - 9}

f (x) = 2^{x}

f (x) = 3 x - 8

(0, 0), (2, 1)

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

What is the domain of f(x)=-4^x ?
The domain of f(x)=-4^x is -infinity <x<infinity
