I am trying to call a function in my JavaScript code, but I keep getting the error “TypeError: undefined is not a function”. Here is my code:

function greet(name) {
    return "Hello, " + name + "!";
}

console.log(greet("Alice"));
console.log(sayGoodbye("Bob")); // This line causes the error

function sayGoodbye(name) {
    return "Goodbye, " + name + "!";
}


Correct the code above correctly
