Answer:
Refer the attached figure.
The new function is 
 
 
Explanation:
Given : The graph of the function 
 is shifted 3 units down.
 is shifted 3 units down.
To find : Draw the transformed function on the provided graph?
Solution : 
When the graph is shifted with 'b' unit downward then the function get subtracted by that unit,

Applying in the given function,
 

h(x) shifted 3 units down,
 

 

Refer the attached figure below for the graph and transformation of function.
