Let R : x is not a positive integer. Define a function asthen f is:
injective but not surjective
neither injective nore surjective
surjective but not injective
One - One or Injective function -
A function in which every element of range of function corresponds to exactly one elements.
A line parallel to x - axis cut the curve at most one point.
This can be written as
f is one-one i.e injective but not surjective.
