Question

The graph below does not represent a function. The vertical line is not part of thegraph, but may be used to answer the question below.List the minimum number of point(s) that you would need to remove to make the grapha function. For example: (1,2), (3, 4). Please see picture

Answer 1

(10, 8), (5, 5)

Step-by-step explanation:

Note that for a graph to be considered to represent a function, each of the input values (x-values) must be paired with exactly one output value (y-value).

Looking at the given graph, we can see that at the point x = 10, y = 4, and y = 8 and at the point x = 5, y = 2, and y = 5. These are the points that make the graph not represent a function because there is more than one y-value for each x-value.

Therefore, to make the graph a function, we would need to remove the listed points; (10, 8), (5, 5)
