Functions, Inputs, and Outputs OH MY!!

The video tutorial introduces the concept of graphs and functions, focusing on the relationship between inputs and outputs in functions. It explains that a function is a relationship where an input is processed to produce an output. The tutorial provides an example using the equation 4X = Y, where X is the input and Y is the output, illustrating how changes in the input affect the output.

Provide an example of a function and describe its input and output.

What does it mean when we say a function can move up or down?
