Angelica is working with function machine she has the two machines shown at right she wants to put them in order so that the output of the first machine becomes the input of the second. her initial input is six

Draw a sketch to illustrate the elaborate diagram provided.

The first machine receives the number 6.
It operates on 6 to produce
√(6 - 5) = +1 or  -1
The first machine does not provide a one-to-one functionality.

The second machine receives either 1 or -1.
If it receives +1, it outputs
  (+1)² - 6 = 1 - 6 = -5
If it receives -1, it outputs
  (-1)² - 6 = 1 - 6 = -5

When working in unison, the two machines provide a one-to-one functionality, because the second machine "corrects" the loss in functionality of the first machine.


The two machines work together to provide a one-to-one functionality.

The answer that i got was 8/3
