Determine whether the data in the diagram is a function, and state the domain and range.
blue side red side
1 3
5 4
9 6
3 9
7
14
The domain is:
The range is:
yes the relation is a function
no the relation is a function
To determine if the data in the diagram is a function, we need to check if each input (blue side) has only one corresponding output (red side).
Looking at the data:
1 -> 3
5 -> 4
9 -> 6
3 -> 9
Each blue side (input) has a unique red side (output), so the data is a function.
The domain is the set of all the input values. In this case, the domain is {1, 5, 9, 3}.
The range is the set of all the output values. In this case, the range is {3, 4, 6, 9}.
