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 alpha-cut 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)} |
