If (f:\mathbb{Z}\to\mathbb{Z}) is defined by (f(x)=x^2), which statement is correct?यदि (f:\mathbb{Z}\to\mathbb{Z}) को (f(x)=x^2) से परिभाषित किया गया है, तो कौन-सा कथन सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is a function because every (x\in\mathbb{Z}) has one definite imageयह फलन है क्योंकि हर (x\in\mathbb{Z}) की एक निश्चित छवि है
For every integer (x), (x^2) gives one definite integer. Having the same image does not break the function condition.हर पूर्णांक (x) के लिए (x^2) एक निश्चित पूर्णांक देता है। समान छवि आना फलन की शर्त नहीं तोड़ता।
