Scatter Graph
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
They mean the graph/function is decreasing.
It is Discrete Graph .

Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
The vertical line test can be used to determine if a graph is a function. If two points in a graph are connected with the help of a vertical line, it is not a function. If it cannot be connected, it is a function.

Since there are no "following" points, none of them.
The function is not continuous.
