Explanation:

The rule is

A relation is said to be a function if every domain has an unique range

  • y=f(x)

Here

f(4) has 2 values 2,3 hence it's not an function

Answer:

  • No

Explanation:

According to the definition of the function each domain should have a uniqe range.

We have same domain of 4 with two different ranges 2 and 3.

It makes the relationship one-to-many, which can't be a function
