Introduction to Programming Extra Credit Exercise - Function

Anyone knows what to do with b and c, for the Introduction to Programming Extra Credit exercise? Rather stuck with these two.

This is the question: Create a function that takes 3 arguments, a, b, and c. If a is an even number have the function return the string "even". Otherwise have the function return the string "odd"

So far this is how far I've come:

var sayABC = function (a, b, c) {
    if (a % 2 == 0) {
        document.write ("even");
    } else {
        document.write ("odd");
    }
}

This worked for me but can anyone recommend a better way?

var a = parseInt (prompt ("Enter a number for A"), 10);
var b = parseInt (prompt ("Enter a number for B"), 10);
var c = parseInt (prompt ("Enter a number for C"), 10);

sayABC(a, b, c);

function sayABC (a, b, c) {
    if ((a + b + c) % 2 == 0) {
        document.write ("even");
    } else {
        document.write ("odd");
    }
}

Maybe this? It could be an instance where a is an input, but you must include it in the equation to come out with the correct answer. You can really interpret it how you want, they just want you to see you can have more than 2 arguments.

var sayABC = function (a(apples in the basket), b(bad apples take out of the basket), c(collected apples added to the basket today)) {

a = (a + c) - b;

if (a % 2 == 0) {

return "even - basket is good, you can stop";

}

else

return "odd - basket is not right, keep picking";

}

}
