Answer:
"s" is the name of the function.
Explanation:
We are dealing with a function.
"s" is the name of the function. We typically use "f" to represent the function but using other letters is fine too.
(A) is the domain or input value for the function that we solve for. Since we are given A, that will be what a equals in the function.
4 is the range or output value of the value. Since we are given "4", the range is 4.
Best of Luck!
