Question

At the zoo, each animal has a very specific morning diet. It can be the same for some animals (lions and tigers, for example), but is obviously different among many others. Each animal’s diet does not vary or change from day to day, however. If the animal is the input and the morning meal is the output, is this relation a function?

Answer 1

Remember that

The data set is a function if every element of the domain corresponds to exactly one element of the range

In this problem

element of the domain is the input -----> is the animal

element of the range is the output ----> the morning meal

The problem says that

"Each animal has a very specific morning diet. It can be the same for some animals"

but each animal doesn't have two different morning meal

that means

Yes, the relation is a function
