Why function is not returning the value [closed]

var y=0;
var x=0;
function randomNumber1(){
  x=Math.floor((Math.random())*6)+1;
  console.log(x);
  return x;
}
function randomNumber2(){
  y=Math.floor((Math.random())*6)+1;
console.log(y);
  return y;
}
randomNumber1();
randomNumber2();
console.log(randomNumber1);
console.log(randomNumber2);
