Question

can a constant function be (a) one-one and (b) onto? if so when?

Answer 1

$A \: constant \: function \:be \: a \: bijective \\(Both \: one - one \: and \:onto \:at \:a \:time ) \:if :$

• For one - one domain should be singleton (Codomain may have any number of elements )
• For onto codomain should be singleton set(Domain may have any number of elements )
