This problem, we need to identify what sort of relationship exists between the items in a store and their associated price.
00:20
Specifically, we need to identify, is there a one -to -one relationship between the items in a store and their corresponding price values? once one means that, right, for any given input, or we'll say item in this case being the input, any given input has its own unique output value.
01:05
Or we'll say price in this case.
01:13
In other words, different items always have different prices if this is a one -to -one relationship.
01:21
So let's say maybe i have, we're going to say, might have a box of cereal.
01:31
There's one item.
01:33
Maybe i'll have, oh, some sliced turkey.
01:43
There's another item at the store.
01:45
Maybe a gallon of milk.
01:50
The associate prices of these might be something like $350 for the milk, $350 for the cereal, maybe $5 for a pound of sliced turkey.
02:08
So i can see that cereal and sliced turkey are different items with different prices...
