In the graph below, which point could be removed from the graph to make the relation a function?

Question

what is the answer to the question so that I can help my daghter with her homework

Answer 1

if you had two points on the graph such as (1,2) and (1,3) remove either one of them

you can't have two points that have the same x value, but different y values

if you can draw a vertical line through the graph that cuts the graph in more than one point, it's not a function. to make it a function remove one of the two points
