Patterns and Linear Functions

This video shows how patterns in function charts give you different values. Linear functions are where the function output changes at a constant rate, relative to the input.

An example of this would be the function:
 y = 4x
 y = 4(1) = 4
 y = 4(2) = 8
 y = 4(3) = 12
This function increases at a constant rate, as the input increases or decreases at a constant rate.
