Question

how many y-values are there for each x-value in the function represented by the graph?
graph of a coordinate plane with a horizontal line at y = -4
options: 0, 1, 2, infinitely many

Explanation:

Step1: Recall function definition

A function is defined such that each input \(x\)-value has exactly one output \(y\)-value.

Step2: Analyze the given graph

The graph is a horizontal (near-horizontal) line. For any single \(x\)-value on this line, there is only one corresponding \(y\)-value.

Step3: Match to options

This matches the condition of exactly 1 \(y\)-value per \(x\)-value.
