Question 207971: I would to ask on how to solve this problem:
Given f = {(-2,3),(-1,1),(0,0),(1,-1),(2,-3)} and
g = {(-3,1),(-1,-2),(0,2),(2,2),(3,1)}
please find a.) (fog)(0) and (gof)(-1)

You can put this solution on YOUR website! I would to ask on how to solve this problem:
Given f = {(-2,3),(-1,1),(0,0),(1,-1),(2,-3)} and
g = {(-3,1),(-1,-2),(0,2),(2,2),(3,1)}
please find
a.) (fog)(0)= f[g(0)] = f[2] = -3
-----
and (gof)(-1)= g[f(-1)} = g[1] = ?
Can't answer that because g(1) is not defined.
