Answer 1

If you want to use generics, first you have to understand that the name of the variable types starts capitalized and they are names, just that so [Int] in your function is the name of the type variable, an example:

object Main extends App{
    val f: String => Int = s => 4
    println(myfunc(f, "nothing useful"))

    def myfunc[A,B](f:A => B, x: A):B =  {
      f(x)
    }
}

here the names are A and B and the return type is of type B
