Question

1. which ordered pair should be removed so this graph represents a function? a. (1, 3) b. (3, 2) c. (2, 3) d. (4, 4)

Explanation:

Step1: Recall function definition

A function has one - to - one or many - to - one mapping, i.e., for each x - value there is exactly one y - value.

Step2: Check x - values

In the given set of points, the x - value of 2 has two different y - values (y = 1 and y = 3).

Step3: Determine point to remove

To make it a function, we need to remove either (2, 1) or (2, 3). Among the options, (2, 3) is present.

Answer:

C. (2, 3)
