Transcript text: B) A not a function B is a function, but not one-to-one C is a one-to-one function

Solution

Solution Steps

Step 1: Determine if the graph represents a function

To determine if the graph represents a function, we use the vertical line test. If any vertical line intersects the graph at more than one point, then the graph does not represent a function.

Step 2: Apply the vertical line test

By visually inspecting the graph, we can see that there are vertical lines that intersect the graph at more than one point. For example, a vertical line at \( x = -1 \) intersects the graph at two points.

Step 3: Conclude whether it is a function

Since there are vertical lines that intersect the graph at more than one point, the graph does not represent a function.
