Question

Part A: Give the domain and range of the relation.

Part B: Tell whether the relation is a function.

X Y

8 8
6 6
4 4
2 6
0 8

Answer 1

domain is 0 to 8
range is 4 to 8

There is one and only one value of y for each value of x so it is a function.
HOWEVER the inverse of this function is NOT a function
