2. given the expression f(g(k( where f, g, and k are functions, what operation should be
performed first? does the order matter? why or why not?

See explanation

Step-by-step explanation:

The expression is the composition of three functions.

The function composition is an operation that takes two functions f and g and produces a function h such that

Here the function f(x) is the input. The order in function composition matters! You always compose functions from right to left.

So, in your case, the first input is k(x), then the second input is g(k(x)), and only then you'll find f(g(k(x))).

Example:

then

If you change the order of operations, you'll get another result, for example
