Question

is this graph a function? hint: does it pass the \vertical line test?\ yes no rewatch

Explanation:

Step1: Recall Vertical Line Test

A graph is a function if any vertical line intersects it at most once.

Step2: Apply Test to Graph

For the given "S - shaped" graph (symmetric about y - axis), a vertical line (e.g., the y - axis or any vertical line) will intersect the graph at more than one point. So it fails the vertical line test.

Answer:

No (with the checkbox next to "No" selected)
