I'm having a hard time with Scala syntax. I've included the tests that this needs to pass. If you could comment and walk through your code it would be much appreciated.

//BEGIN TEST /* Define functions for the tests */ val f1: Int => Int = (x) => (x+10) val f2: Int => Int = (x) => (-2*x) def f3(x: Int): Int = x*x val f4: Int => Int = (x) => { if (x

/* Some test cases */ testWithMessage(!isOddFunction(f1, 10), "1") testWithMessage(isOddFunction(f2, 100), "2") testWithMessage(!isOddFunction(f3, 100), "3") testWithMessage(isOddFunction(f4, 8), "4") testWithMessage(!isOddFunction(f4, 15), "5") passed(5) //END TEST

A function f:7 Z over integers is a odd function if for all numbers x EZ, f(-x) = -f(x). As an example f(x) = 5x is an odd function. However, f(x) = x2 is not. Write a scala function isOddFunction(f, n) that checks if f(-2) = -f(z) for every number z within the range 1, ... , n. The function should return true if f is indeed an odd function and false otherwise. You may use a for loop for this problem.
