# Math Help - Find the composite gof of the following pair of functions

1. ## Find the composite gof of the following pair of functions

f: {1,2,3,4} ---> {a,b,c,d} given by f = {<1,b>, <2,a>, <3,d>, <4,c>}
g: {a,b,c,d} ---> {v,w,x,y,z} given by g = {<a,v>, <b,x>, <c,w>, <d,z>}

2. $1 \mapsto x$, $2 \mapsto v$, $3 \mapsto z$, $4 \mapsto w$.
