Answer 1

A.up

Explanation:

When you have a function and you add a certain number of units to the function you will be shifting the function that same amount of units up, so for example if your function is y=x.

Then when x=1 y=1

If you add 3 units to that function you will have that when X=1 y=4

So you will be shifting the function 3 units up.
