Answer:
The graph of y = f(x) will shift to the right 9 units.
Step-by-step explanation:
Despite some lack of clarity, because usually this equality is in terms of x and y. Let's do it.
Taking f(x) as its parent function in other words
[tex]y=f(x)[/tex]
Testing some values:
x|y
0|0
1|1
2|2
Adding to the function -9 units is to shift it to the right
[tex]y=f(x-9)[/tex]
Testing some values to certify:
x|y
-9|0-9
-8|1-9
-7|2-9
