2. Given the expression f (g (k (x))), where f, g, and k are functions, what operation should be

performed first? Does the order matter? Why or why not?

The order matters

Step-by-step explanation:

If you answer it in a different order, you will be inputting wrong numbers into each subsequent function generating an incorrect answer.

You must start with the innermost function.

First you evaluate k (x). Then you evaluate g (k (x)).

Finally you evaluate f (g (k (x))).

The order does matter. If you evaluate in a different order, you will be inputting wrong numbers into each subsequent function generating an incorrect answer.
