Three points must be removed from this graph so that it will be a function

How to determine the number of points?

The points are given as:

(-3, 2), (-3, 3), (1, 4), (1, -4), (2, -4), (2, -2).

For a set of point to represent a function;

Each x coordinate must point to only one y coordinate

From the given points, we have the following highlights:

  • The x value -3 has two y values (2 and 3)
  • The x value 1 has two y values (4 and -4)
  • The x value 2 has two y values (-4 and -2)

In the above highlights, one point each must be removed.

This means we have a total of 3 points

Hence, three points must be removed from this graph so that it will be a function
