You need to actually take time to learn and understand javascript. If you're just asking for code on forums and pasting it into your coursework without understanding it then you're not learning anything.

JavaScript

return totalPrice > x;

That returns a boolean value of true or false, and the calculated DiscountPrice value is thrown away after it is calculated. Also, why are you passing in products and totalQuantity since you do not use either value anywhere in your calculation.

Think about the simple steps needed to do this:
the function only needs to know the current total price, and the steps are something like:
1. set newprice = totalprice.
2. if totalprice > x then set newprice = totalprice * .90
3. return newprice // if totalprice is less than x, then original total will be returned
