Decide whether the following relation defines a function. ((5,3), (4,3), (5,2)} Is the set of ordered pairs a function? Yes No

The bar graph to the right shows the average number of hours that people sleep per​ day, by age group. Use this information to complete parts a and   Consider a​ function, f, whose domain is the set of six ages shown. Let the range be the average number of hours that people sleep per day. Write the function as a set of ordered pairs. f= Write the relation that is the inverse of f as a set of ordered pairs. The relation is Based on these ordered​ pairs, is f a​ one-to-one function?   The function f is not a​ one-to-one function because the relation that is the inverse of is a function. B. The function f is a​ one-to-one function because the relation that is the inverse of f is a function. C. The function f is not a​ one-to-one function because the relation that is the inverse of f is not a function. D. The function f is a​ one-to-one function because the relation that is the inverse of f is not a function.

Every function is also a relation.     This statement is true or false
