Question

input = 1: exactly one output, which is 2
input = 2: exactly one output, which is 1
when the input is 3, how many outputs are there?

• exactly one output, which is 2
• exactly one output, which is 3
• more than one output

Explanation:

Step1: Analyze the graph for input x=3

Looking at the coordinate grid, when the x - value (input) is 3, we check the y - values (outputs) associated with x = 3. The points with x = 3 are (3, 2) and (3, 3).

Step2: Determine the number of outputs

Since there are two distinct y - values (2 and 3) for the input x = 3, this means there are more than one output for the input 3.

Answer:

more than one output
