Classwork:
Given and
, we have
(1)
Using the composition found in (1), we have
(2)
(3)
Using the composition found in (3),
(4)
Homework:
Now if , we would have
(1)
For (2), we could explicitly find then evaluate it at <em>x</em> = -1 like we did in the classwork section, but we don't need to.
(2)
(3) We can demonstrate that both methods work here:
• by using the result from (1),
• by evaluating the inner function at <em>x</em> = 2 first,
