Answer:
Option A is correct
 
 
Step-by-step explanation:
Vertically down:
To  translate the absolute parent function y=f(x) vertically, the new function we get;
g(x) = f(x) + k 
when k < 0 , the function is vertically down 
when k > 0, then the function is vertically up
Given the function:
The translation of y = |x|
To do vertically down with 15.5 
Use the above definition we have;
 
 
Therefore,  an equation for the translation of y = |x|, with 15.5 units down
is,
