Answer:
Step-by-step explanation:
Alright, lets get started.
When we add or subtract any thing from the function f(x), that is called vertical shift.
The vertical shift means graph will move up or down.
When something is added, the graph of f(x) goes up means vertical shift up.
When something is subtracted, the graph of f(x) goes down, means vertical shift down.
So, when 11 is subtracted from f(x), it means, the graph of f(x) will shift 11 units down. : Answer
