1.	Angelica is working with functionmachines. She has the two machinestherm in order so that the output of thefirst machine becomes the input ofthe second. Her initial input is 6.a. In what order must she put the machines to get a final output of 5?b. Is it possible for her to find an initial input that will get a final output of -5If so, show how she could do that. If not, explain why not.
Answer» x = 6a. Second machine first.y = x² - 6 = 36 - 6 = 30y = √x - 5 = √30 - 5 = √25 = 5 b. Yes, it is possible. Give the input initially in the first machine. y = √x - 5 = √6 - 5 = 1 y = x² - 6 = 1 - 6 = -5

Answer»

x = 6a. Second machine first.y = x² - 6 = 36 - 6 = 30y = √x - 5 = √30 - 5 = √25 = 5

b. Yes, it is possible. Give the input initially in the first machine. y = √x - 5 = √6 - 5 = 1 y = x² - 6 = 1 - 6 = -5
