1. Try a few different inputs. Are you surprised by your results?

2. Carrie claims that she was not surprised by her results, and she can show you why by using an input of $c$. Input $c$ into the stack of function machines and show all of the steps. What happens?
input: $c$
Function 1: $(c)−5=c−5$
Function 2: $\frac{6(c-5)+8}{2}=\frac{6c-30+8}{2}$
Simplify the output of Function 2, and then substitute it for $x$ in Function 3.
