Que.  Consider a fuzzy set old as defined below
Old = {(20, 0.1), (30, 0.2), (40, 0.4), (50, 0.6), (60, 0.8), (70, 1), (80, 1)} Then the alphacut for alpha = 0.4 for the set old will be 
a.  {(40,0.4)} 
b.  {50, 60, 70, 80} 
c.  {(20, 0.1), (30, 0.2)} 
d.  {(20, 0), (30, 0), (40, 1), (50,1), (60, 1), (70, 1), (80, 1)} 
Answer:{(20, 0), (30, 0), (40, 1), (50,1), (60, 1), (70, 1), (80, 1)}
