Question

Identify whether the given situation represents one-to-one function. Justify your answer.8)Birthdate of a family member 9.) The relation pairing a person to his or her telephone number. 10.)The relation pairing a television to universal remote control.

Answer 1

A one-to-one function are functions that have a unique range for every input of the domain.

A birthdate of a family member CANNOT be considered a one-to-one function BECAUSE it is possible that two of the family members will share the same birthday. In that case, their birthdays will not be unique for themselves anymore.
