Question

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?

Answer 1

The order matters

Explanation:

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

Answer 2

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.
