5-29.

Lacey and Richens each have a personal function machine. Lacey’s machine, , squares the input and then subtracts

*, adds*

Write equations that represent

and.Lacey and Richens decide to connect their two machines so that Lacey’s output becomes Richens’ input. If

is the initial input, what is the final output? What if the order of the machines is changed? Would it change the output? Justify your answer.

Try computing the result for

if the order is reversed.
