Fonksiyondur.
Fonksiyon değildir.
Answer explanation
Fonksiyon değildir. Bir bağıntının fonksiyon olabilmesi için bir elemanın sadece bir görüntüsü olması gerekir. x yerine örneğin 0 verdiğimizde |y|=1 olur. Buradan da y=1 ve y=−1 değerleri çıkar, tanım kümesinden bir eleman değer kümesinden iki elemanla eşleşmek zorunda kalır.
