    But it is given that x = 0 Then how is the line going on both sides of the y axis? It would mean that on either side, x has some non-zero value.

    0!=1 olması kabüldür. Çünkü Bir n doğal sayının faktöriyelini n ye eşit veya n den küçük sayma sayılarının çarpımı olarak tanımlarsak, 0! ifadesi 0'a eşit veya 0’dan küçük bütün sayma sayılarının çarpımı olur. Ancak çarpılacak sayıların oluşturduğu küme boş kümedir. Yani çarpma işlemini "hiç defa" yapmak gerekir. Çoğu kez bir nesneyi kendisiyle sıfır defa bir küme üzerinde işleme koymak; eğer varsa bizi, o işlemin o kümedeki birim(etkisiz) elemanına götürür. Böylecede işlemin o küme üzerindeki birim(etkisiz) elemanına bir kabül getirilmiş olur. Yani 0!=1 dir. Şöylede izâh edebiliriz : n! sayısını n elemanlı bir kümeden yine kendisine tanımlanan bire-bir ve örten fonksiyonların sayısı olarak tanımlarsak, 0! ifadesi, boş kümeden boş kümeye tanımlanan bire-bir fonksiyonların sayısı olacaktır. Bu yüzden 0!=1 olmalıdır. (n+1)!=(n+1).n eşitliği 0!=1 kabülü ile n=0 için de doğrulanır. Yani bu kabül işimize yarayan kanonik bir seçim olmaktadır. Eğer 0!=1 kabülü bazı işlerimizi zorlaştırsaydı tanımsız da bırakılabilirdi. Bu biraz da çalışılan alanın tabiatı ile ilgili. (n+1)!=(n+1).n! eşitliği her n sayısı için geçerli değildir. Yani bu eşitlik bir özdeşlik değildir. Mesela n yerine -1,0,1/2 gibi sayılar verilemez. Çünkü (-1)! , 0!, (1/2)! İfadeleri tanımsızdır. 0! tanımsız olduğundan kanıttan da bahsedilemez. Peki bunu nasıl yorumlayacağız? Yukarıdaki eşitlikte n yerine 0 yazarsanız 1!=1.0! olur ki tanımsız bir ifadenin 1 ile çarpımı gündeme gelmektedir. Bundan dolayı 0!=1 sonucunu çıkarmak yanlıştır. Bu açıklamalarıma rağmen illede buradan 0!=1 olur derseniz o zaman yukarıdaki eşitlikte n yerine -1 yazın. 0!=0.(-1)! dan 0!=0 olur ki! Şimdi 0! , 1'e mi eşit 0'a mı eşit? Matematikçiler, kombinatorik dersinde 0!=1 eşitliğinin bir sorun yaratmadığını da gördükleri için 0!=1 olduğunu kabül etmişlerdir. Bildiğim kadarıyla mühendislikte ihtiyaç zuhur ettiğinden " ! " notasyonu mevcut tanımıda içerecek şekilde negatif ve kesirli sayılara da uyarlanmıştır. Bu aşamada matematikçiler " Gamma Fonksiyonu " isimli bir fonksiyon tanımlamış, bu da mühendislerin bu anlamda ihtiyaçlarını gidermiş. 0!=1 i şöylede anlayabiliriz : 3 kişi bir tahtanın önünde 3!=6 foto çektirebilir. 2 kişi bir tahtanın önünde 2!=2 foto çektirebilir. 1 kişi bir tahtanın önünde 1!=1 foto çektirebilir. tahtanın önünde hiç kimse yoksa boş tahta 0!=1 şekilde çekilebilir. ( O foto da tahtanın kendisidir. )
