The relation is not a function.
Step-by-step explanation:
By definition, a relation is a function if each input value has only one output value.
Given the relation:
(4,23)
(3,-2)
(-6,5)
(4,6)
The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):
{}
The range is the set of the y-coordinates of each ordered pair :
{}
Since the input value 4 has two different output values (23 and 6), the relation is not a function.
Answer:

to get 9,
(330/5) =66
66 multiplied by 9 =594
therefore 9 will cost 594p
