7. Identify whether the following ordered pairs is a function: (2, 2), (3, 2), (5, 4).

Pick a destination for a hypothetical road trip. What is the distance in miles?   If you are traveling this road trip, the distance remaining can be described as a function of miles driven. Use function notation to write a mathematical function to describe the distance remaining. Use x for the domain and for the range. Identify 3 ordered pairs that fit within the domain and range of your function. Use these three ordered pairs to graph the function

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.
