Question

the set of ordered pairs (1,8.50), (3,25.50), (5,42.50), (6,51), (7,59.50) represents the cost of tickets for the school play for different numbers of tickets. the input represents the number of tickets and the output represents the total cost. is the cost a function of the number of tickets? explain
the relation ▼ a function because ▼ is assigned ▼

Explanation:

A function is defined such that each input (domain value) has exactly one corresponding output (range value). Looking at the given ordered pairs: (1, 8.50), (3, 25.50), (5, 42.50), (6, 51), (7, 59.50), every input (number of tickets) is unique and maps to only one output (total cost). No input is assigned more than one output.

Answer:

The relation is a function because each input (number of tickets) is assigned exactly one output (total cost).
