Answer:

The graph of y = f(x) will shift down 9 units.

Step-by-step explanation:

With the graph of y = f(x)-9  the graph of y=f(x) will shift down 9 units. For example:

if f(0) = 0, then y = f(0) -9 = -9.

if f(1) = 9, then y= f(1) - 9 = 9-9 = 0.

The same proccess with all x in the domain of f(x).
