Answer:
A. down
Step-by-step explanation:
The parent graph is
[tex]f(x) = x[/tex]
If this graph is transformed to obtain
[tex]g(x) = f(x) - 4[/tex]
The subtracttion means the graph will shift downward vertically
The graph of g(x) is obtained by shifting f(x) down by 4 units.
Therefore the direction is down.
