The bar graph shows minimum legal ages for sex and marriage in five selected countries. Use this information to solve Exercises 99–100. (We did not include data for the United States because the legal age of sexual consent varies according to state law. Furthermore, women are allowed to marry younger than men: 16 for women and 18 for men.)
a. Write a set of five ordered pairs in which countries correspond to the minimum legal age of sexual consent. Each ordered pair should be in the form
(country, minimum legal age of sexual consent).
b. Is the relation in part (a) a function? Explain your answer.
c. Write a set of five ordered pairs in which the minimum legal age of sexual consent corresponds to a country. Each ordered pair should be in the form
