Question

check the box corresponding to each graph that represents a function.

Explanation:

Step1: Recall Vertical Line Test

A graph represents a function if no vertical line intersects the graph more than once.

Step2: Apply to the Given Graph

The given graph is a straight line (linear graph). For any vertical line \( x = a \) (where \( a \) is a real number), it will intersect the linear graph at most once. So, this graph passes the vertical line test.

Answer:

The given graph represents a function (so we check the box corresponding to this graph as it passes the vertical line test).
