Question

when the input is 1, how many outputs are there? exactly one output, which is 1 exactly one output, which is 2 more than one output

Explanation:

Step1: Identify x=1 on graph

Locate \( x = 1 \) on the x - axis of the coordinate grid.

Step2: Check corresponding y - value

At \( x = 1 \), there is one point with \( y = 2 \). So, for input \( x = 1 \), there is exactly one output (y - value), which is 2.

Answer:

exactly one output, which is 2
