Question

Which statement best describes if the relation (c, f) is a function?

Answer 1

Answer:

The graph is not a function of x because the line x=0 intersects the graph at two points

Step-by-step explanation:

For any function of x, x can only map to one point. What this means is that for every x value, it only results in one y value. If you can input x into the relation's equation and get two outputs, the relation is not a function.

We can check if an x value maps to two points by using a vertical line, such as x=0, and if it crosses the relation at two points, the relation is not a function.

Since x=0 crosses the line at two points, it means that this relation is not a function.
