For the relation
R = { ( x , y ) ∣ x ≤ y }
defined on N (natural numbers), R-1 is
Group of answer choices
R^−1={(x,y)∣y>x}
R^−1={(x,y)∣y≤x}
R^−1={(x,y)∣y≥x}
R^−1={(x,y)∣x>y}
None of the above
Here
R-1 is
R-1={(x,y)∣y≤x}
Answer (B)
Please give thumbs up if you like the answer.
Let R be the relation defined on Z (integers): a R b iff a + b is even. R is an equivalence relation since R is: Group of answer choices Reflexive, Symmetric and Transitive Symmetric and Reflexive or Transitive Reflexive or Transitive Symmetric and Transitive None of the above
Let R be the relation defined on Z (integers): a R b iff a + b is even. Then the distinct equivalence classes are: Group of answer choices [1] = multiples of 3 [2] = multiples of 4 [0] = even integers and [1] = the odd integers all the integers None of the above
