Answer:
The correct option is A) Down.
Step-by-step explanation:
A function can be shift vertically up or down by adding some positive or negative constant.
For example:
Consider the figure 1:
The function shifted up by <em>k</em> unit. (where <em>k</em> is 1 unit)
Now consider the figure 2:
The function shifted down by <em>k</em> unit. (where <em>k</em> is 1 unit)
Which means to shift the graph of an equation certain number of units up, we need to add that number from the functions equation.
Similarly, to shift the graph of an equation certain number of units down, we need to subtract that number from the functions equation.
Therefore, the correct option is A) Down.
