Function or not a function?

If we want to check that a graph is function or not, we have a way to check by doing these steps.

If a line intercepts a graph only one point, a graph is indeed a function. Otherwise, not a function but a relation instead. That includes if a line intercepts more than a point which doesn't make a graph a function.

From the graph, if we follow these steps, we will see that a line will only pass or intercept the graph only one point. Hence, the graph is indeed a function. The following graph that is shown is called "Parabola" for a < 0.

The graph is a function.

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

because its not ur topic and its not for is for homework not that.
