Homework Statement
Let g : A → B and f : B → C where A = {a,b,c,d}, B = {1,2,3}, C = {2,3,6,8}, and g and f are defined by g = {(a,2),(b,1),(c,3),(d,2)} and f = {(1,8),(2,3),(3,2)}.
Find f o f
Homework Equations
The Attempt at a Solution
I know how to find f o g by working from g to f, but I'm not sure what to do with f o f. Does it simply map back to it self?
Thanks for any suggestions.
