The first machine describes a function of the variable n. The first one is the "add 2 then multiply by 3 function". So if we call the output f(n) it's f(n)=3(n+2) Since we work what's in parentheses first, this ensures we do the steps in the right order. The second one is a function of x. It is the "multiply x by 4 then add 5" function. So the steps are "Times 4" Then "Add 5"
