Question

Which of the following points could you remove so that the resulting graph is the graph of a function?

A. (-2, -3)
B. (-1, -5)
C. (0, 5)
D. (1, -3)

Answer 1

(-2,-3) OR (1,-3) could be removed so that the graph is a function. a function has one x-value for each y-value.

Answer 2

(1, -3) can be removed so that the resulting graph represents a function. A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y
