13. Determine whether a relation is a function, defining a function as a rule that assigns to each input (independent value) exactly one output (dependent value), and given a graph, table, mapping, or set of ordered pairs.
[MA2019] ACC-8 (8) 18 :
18. Compare and contrast relations and functions represented by equations, graphs, or tables that show related values; determine whether a relation is a function. Identify that a function f is a special kind of relation defined by the equation y = f(x). [Algebra I with Probability, 16]

Title: Introduction to Functions and Equations for Functions
URL: https://aptv.pbslearningmedia.org/resource/our20-math-8523/introduction-to-functions-and-equations-for-functions/
Description:

In this video lesson, students learn the term function for a rule that produces a single output for a given input. This lesson introduces and connects the different ways in which we represent functions in mathematics: verbal descriptions, equations, tables, and graphs. Students transition from input-output diagrams and descriptions of rules to equations. The lesson also introduces the use of independent and dependent variables in the context of functions.
