This is a properly written function expression and functions can be passed into variables in JavaScript

You can pass functions into variables as in "var result = subtract(4,3);" but you must use the "new" operator when creating the function

True

This is a properly written function expression, but an error occurs when you pass the function into a variable

False

There is a syntax error since there is a ";" semicolon after the function close bracket '}'

The function is written wrong, there should be a function name and no variable in front. You get another error when you try to pass the function into a variable during "var result = subtract(4,3);"

If you had defined the function like this "function subtract(x, y) { ... }" then it would be the correct way to declare the function and then "var result = subtract(4,3);" would also work.
