You've defined the function wrong. Functions are defined by

function name(parameters) {

}

where function is a keyword to define the function, name is the name of your function, and parameters are the values you want your function to accept (basically variables within your function). So your task is to create a function called max, which accepts two parameters and returns the bigger value.

function max(x, y) {

}

we first start off by defining the function, calling in max, then we give it two parameters. Now all we need to do is give the logic, to solve our problem. This can be achieved with a simple if else conditional statement.

function max(x, y) {
  if(x > y) {
    return x;
  } else {
    return y;
  }
}
