Angelica is working with function machines. She has the two machines
In what order must she put the machines to get a final output of 5?
Try substituting 6 for x in g(x) and then input the result into h(x). If that does not work, switch the order.
Substitute 6 for each x.
Substitute the output of the first function for x in the second function.
The output needs to be 5.
Is it possible for her to get a final output of −5? If so, show how she could do that. If not, explain why not.
See above (original incorrect solution).
