Function Machines. How To Find The Input Of A Function Machine If You Are Given The Output.

Function: Represent Change -2-Step Rules – Mixed Operations (Function Machine). Functions are relationships between pairs of numbers. Function machines represent functions using an input and output model where numbers enter a ‘machine’ and are operated on and then exit the machine changed. Single step function machines involve one operation. This lesson introduces 2-step functions where two operations are performed on the input number in order. By having the two machines inline the order of the
