Answer:

Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D

Explanation:

Take a look at the procedure below;

First simplify f ( x ) = - 4 * ( 8 )^x, such that it is ⇒

f ( x ) = - 2^2 * 8^x,

f ( x ) = - 2^2 * ( 2^3 )^x,

f ( x ) = - 2^2 * 2^3x,

f ( x ) = - 2^2 + 3x,

Now if we take a look at the domain we can see that it has no undefined points nor domain constraints, thus;

- ∞ < x < ∞

However, the range of the function is present in the form - c * n^ax + b, where f ( x ) < k, and k = 0;

f ( k ) < 0, y < 0

Solution; Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D
