Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The answer is you have to remove 4 points.
There is 6 points in all and for a function it only needs two points to become a function. A function needs to be a that line that passes the vertical line test. For example: A circle is not a function because when you perform the vertical line test you'll see that many points share a common x-value and a function needs only one output in every input.
