Let X denote the set of all real-valued functions defined on Z. Define a relation -in X by f ~ g if f(0)1 g(0). Then the relation ~ is
  • a)
    both reflexive and symmetric
  • b)
    neither reflexive nor symmetric
  • c)
    transitive but not reflexive
  • d)
    neither transitive nor reflexive
Correct answer is option 'D'. Can you explain this answer?

Given that X denote the set of all real valued functions defined on Z. Define a relation in X by f ~ g if f(0) ≠ g(0).
So, f(0) ≠ f(0) which fails reflexive relation.
If wetake f(x ) = 1- x
g(x) = x - l
Here , f(0) ≠ g(x) and we take h(x) = 1 - 2x
Here g(0) ≠ h(0)
But f(0)= h(0).
This fails transitive relation.
Hence, option (d) is correct.

Relation ~ in X

The relation ~ is defined on the set X of all real-valued functions defined on Z (the set of integers). The relation ~ is defined as follows: f ~ g if f(0) < g(0),="" where="" f="" and="" g="" are="" functions="" in="" />

Reflexivity

A relation is reflexive if every element in the set is related to itself. In other words, for every function f in X, f ~ f. In this case, for a function f to be related to itself, we would need f(0) < f(0).="" however,="" this="" is="" not="" possible="" since="" a="" number="" cannot="" be="" less="" than="" itself.="" therefore,="" the="" relation="" ~="" is="" />not reflexive.

Symmetry

A relation is symmetric if whenever f is related to g, g is also related to f. In other words, if f ~ g, then g ~ f. In this case, if f(0) < g(0),="" it="" does="" not="" imply="" that="" g(0)="" />< f(0).="" therefore,="" the="" relation="" ~="" is="" />not symmetric.

Transitivity

A relation is transitive if whenever f is related to g and g is related to h, then f is related to h. In other words, if f ~ g and g ~ h, then f ~ h. In this case, if f(0) < g(0)="" and="" g(0)="" />< h(0),="" it="" implies="" that="" f(0)="" />< h(0).="" therefore,="" the="" relation="" ~="" is="" />transitive.

Conclusion

Based on the analysis above, we can conclude that the relation ~ is neither reflexive nor symmetric, but it is transitive. Therefore, the correct answer is option D) neither transitive nor reflexive.
