Misae says that a step graph does not represent a function because the graph is not connected. alex says that it does represent a function because there is only one y for every x. who is correct and why?

alex is correct

step-by-step explanation:

Hi, you for posting your question here at

a step graph is still a function, but not continuous. this means that there are some set of x-coordinated that don't have a corresponding y-coordinate, or vice versa. discontinuous or discrete functions are still functions.
