What is a relation and what makes it different from a function? How can you determine the domain and range of a function?

Step-by-step explanation:

A function is the relation that takes the inputs of the domain and output the values in the range. The rule for a function is that for each input there is exactly one output. Mapping of a Function: The oval on the left is the domain of the function f , and the oval on the right is the range.

I hope it's helpful!

Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98
