Functions 01: What is a Function?

Welcome to MathforAll! 

In this video, we are going to learn about relations and functions

  • We explain the three main ways of showing relations: mapping, list of points, and graphing.
  • We define a function as every time I put in an x value, I get the same y value
  • We determine whether relations are functions using mapping, list of points, and graphing (vertical line test)
