I'm thinking that they want you to state (using English) the operations (in order) for evaluating the expression. In other words, what happens to the number x while changing it into y ?
Here's an example.
y = 4(x - 2)^2 - 7
We could state the rule like so:
"Variable y is defined by multiplying the square of the difference between x and 2 by 4 and subtracting seven."
"The rule for y is: (1) decrease x by 2; (2) square the result; (3) multiply by 4; and (4) subtract seven."
"This function reduces it's input by 2 and squares the result, followed by increasing by a factor of 4 and then reducing by 7."
Just describe what you would do to x, in order to calculate y.
