week 13 – function

During this week in math, we learned about a function.

A function is a special type of relation in which each element of the domain is realted to exactly one element of the range.

For example – 1,a) is a function because the inputs did not repeat.

To find the functions – For graphs you could determine which relation is a function by finding vertical lines

-For the arrow diagram, if one onput is mapped to more than one output It’s not a function

– For the ordered pairs if the input value, is repeated is not a function
