Question

Does this table represent a function? Why or why not

Answer 1

Answer: D) Yes, because each x value corresponds to exactly one y value

The table doesn't mention x, but usually x is in the left column. Since we don't have any repeated x values here, this means each input goes to exactly one output. So we have a function.

Visually if you plotted all the points, you'll see the graph passes the vertical line test.
