To calculate: Justify whether each relation is a function.
Answer to Problem 2CYU
The given relation is not a function.
Explanation of Solution
Given:
X | 1 | 3 | 8 | 7 | 3 |
Y | 4 | 2 | 9 | 6 | 4 |
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:
The domain 3 value is paired with two ranges 2 and 3.
Therefore, the given relation is not a function
