A “CHAIN” OF FUNCTIONS Homework Help ✎

Remember that composite functions are made by “chaining” simpler functions together. For example, is made by chaining the functions

*and*

*.*

It can be useful to show this idea with an arrow diagram:

Above is an arrow diagram for * *followed by

*, which is written*

*. (Notice that the “inner” function is applied first.)*

Let . Draw an arrow diagram and determine the composite function for each part below. Simplifying is not required.
