Answer:
it is not a function because there is a domain that has two different ranges
Step-by-step explanation:
so (3,6) and (3,5) have the same domain but different ranges. this means that is cannot be a function. i have a way to remember this. my teacher once told me that the domain is like the ingredients in a recipe. you can use different ingredients and get the same outcome(like a cake) but cannot use the same ingredients and get a different outcome. so you can have different domains with the same range, but never the same domain and different ranges
