Lacey and Richens each have their own personal function machines. Lacey's, L(x), squares the input and then subtracts one. Richen's function, R(x), adds 2 to the input and then multiplies the result by three. Homework Help ✎
Write the equations that represent L(x) and R(x).
Lacey and Richens decide to connect their two machines, so that Lacey's output becomes Richens' input. Eventually, what is the output if 3 is the initial input?
What if the order of the machines was changed? Would it change the output? Justify your answer.
L(x) = x2 − 1
R(x) = 3(x + 2)
Try computing the result for x = 3 if the order is reversed.
