The answer is letter a

Answer:

Option: A is the correct answer.

A. The graph of f(x) is shifted four units down from the graph of g(x).

Step-by-step explanation:

We know that for any parent function g(x) the transformed function g(x)+k is a shift of the function g(x) k units up or down depending on the value of k

i.e. if k>0 then the shift is k units up

and if k<0 then the shift is k units down.

Hence, here we have parent function g(x) as:

[tex]g(x)=-2^{3x}[/tex]

and we are given transformed function f(x) as:

[tex]f(x)=-2^{3x}-4[/tex]

This means we have k=-4<0

This means that the function f(x) is the shift of the parent function g(x) 4 units down.
