domain of f(x)=-0.2^{2-x}-2

domain

f (x) = - 0. 2^{2 - x} - 2

- \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{x}{2 x - 3}

f (x) = (x + 5)^{2} - 3

\frac{2 x}{4} - 2

f (x) = \frac{4}{3 - t}

x^{2} + 3 x - 10

What is the domain of f(x)=-0.2^{2-x}-2 ?
The domain of f(x)=-0.2^{2-x}-2 is -infinity <x<infinity
