The image you uploaded presents a graph and a question: "Is the graph a function?" with options "A) Yes" and "B) No."

To determine if a graph represents a function, we can apply the Vertical Line Test. According to this test, if any vertical line drawn through the graph intersects the graph at more than one point, then the graph does not represent a function. If every vertical line intersects the graph at most once, then the graph does represent a function.

In this case, the graph appears to be a parabola, which is the graph of a quadratic function. A vertical line drawn anywhere on this graph will intersect it at only one point. Therefore, the graph is indeed a function.

The correct answer is A) Yes.
