If (f:R\to R), (f(x)=x^2+1), what is (f^{-1}({5}))?यदि (f:R\to R), (f(x)=x^2+1), तो (f^{-1}({5})) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ({-2,2})({-2,2})
Step 1: For the preimage, solve (x^2+1=5). Step 2: This gives (x^2=4). Step 3: Hence (x=2) or (x=-2), so the preimage is ({-2,2}).चरण 1: पूर्वछवि के लिए (x^2+1=5) हल करें। चरण 2: इससे (x^2=4) मिलता है। चरण 3: इसलिए (x=2) या (x=-2), अतः पूर्वछवि ({-2,2}) है।
