This week, I learned what a function is!

A function is a special type of relation that amkes it so that there arent ever 2 x points on a graph that are overtop of each other. So for example, if you have a graph that’s just a straight line going from one side of the graph to the other, it would be considered a function, but if there’s a graph with a line that curves in almost anyway (there’s some functions that curve and look like they would be relations but actually arent) then it’s a relation.

here’s a picture to help visulally demonstrate what I mean… (R=relation, F=function)
