making / of the recipe. How many cups of flour do you

1 1/8

Step-by-step explanation:

2 1/4/2

9/4 divieded by 2/1=9/8

or 1 1/8

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
