what is the largest value of x that would make the folllowing list of points not a function.

Question

(___,13),(9,16),(13,20)

Answer 1

The largest value of x that would make the list of points not a function is 13. This is because the point (13,20) would create a vertical line if mapped on a coordinate plane, which violates the definition of a function where each input (x) corresponds with only one output (y).
