Consider a function machine that accepts inputs as ordered pairs. Suppose the components of the ordered pairs are natural numbers and the first components is the length of a rectangle and the second is its width. The following machine computes the perimeter (the distance around a figure) of the rectangle. Thus, for a rectangle whose length,
a. For each of the following inputs, find the corresponding output
b. Find the set of all the inputs for which the output is
c. What is the domain and the range of the function?
