Can you give me some hint please
6x.
You cannot figure this one out, unless you know the value of x.
Hope that helped.
Answer:

Step-by-step explanation:
Given


Required

Initial expression of f(x) is 
From the question; we understand that f(x) was shifted down by 3 units;
This implies that

Also from the question; we understand that this new f(x) is equivalent to g(x);
In other words;

Substitute
and 
This gives

<em />
Subtract 0.5x to both sides

Rearrange


Multiply both sides by -1
