Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) − 9?
a) the graph of y = f(x) will shift up 9 units.
b) the graph of y = f(x) will shift down 9 units.
c) the graph of y = f(x) will shift left 9 units.
d) the graph of y = f(x) will shift right 9 units.

we know that

The rule of the translation in this problem is equal to

That means

The translation is units down

therefore

the answer is the option B

The graph of y = f(x) will shift down units.
