To calculate: Justify whether each relation is a function.
Answer to Problem 1AGP
The given relation is a function.
Explanation of Solution
Given: {(5,1),(6,3),(7,5)(8,0)}
The relation is said to be function, if every single element of the domain is associated with one element of the range.
Domain: The domain the set of possible input values, which are shown on the x-axis.
Range: The range is the set of possible output values, which are shown on the y-axis.
Check the domain and range of the given relation:
It can be seen from above that each domain have a single range.
Therefore, the given relation is a function
