Answer:

B) shifts left by 9 units

Step-by-step explanation:

f(x) = |x|

f(x + 9) will shift the graph of f(x) 9 units to the left (see image below).

f(x - 9) will shift the graph of f(x) 9 units to the right.

C) and D) are wrong, becausethe minimum value of f(x) = 0 no matter what we add or subtract from x.
