In week 13 in math 10 we learned how to tell the difference between a relation and a function and what they are, we learner what and input and output were, what a independent and dependant variable is, we learned how they are graphed and 5 ways to express them which can be by a table of value, ordered pairs, graphing, an equation and a mapping graph.

Independent, input, x and range all mean the same thing.

Dependant, output, y and domain all mean the same thing.

Relation- numbers that have common multiple, numbers may varie in similarity.

Function- numbers that have no common multiples and they are singular meaning no number will be the same.
