Answer:it is function and it is 25
Step-by-step explanation:it is 25 in the y inputs because every time the x input increases by one the y input increases by 25
it is a function because each one of the “x” imputes has there own “y” input and if they all have there own that makes it a function. but it there were 2 “y” inputs pointing to one “x” input that would make it a non function
