If (f(x)=\frac{1}{x-2}) and the domain is taken from natural numbers, which (x) cannot be in the domain?यदि (f(x)=\frac{1}{x-2}) और domain natural numbers में से लिया जाए, तो कौन-सा (x) domain में नहीं हो सकता?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2)(2)
At (x=2), the denominator becomes (0), so (f(2)) is not defined. In a rational function, the denominator must not be zero.(x=2) पर denominator (0) हो जाता है, इसलिए (f(2)) defined नहीं है। rational function में denominator zero न हो, यह जरूरी है।
