Answer 1

I can’t see the graphs you mean. Please either upload the images or describe each graph (circle, line, parabola, vertical line, etc.).

Tip so you can check yourself: use the vertical line test — a graph represents a function exactly when no vertical line intersects the graph in more than one point. In other words, each x-value must correspond to at most one y-value.

If you post the images or descriptions I’ll tell you which choice is a function.
