If (f(x)=|x+1|), what is the set (f^{-1}({4}))?यदि (f(x)=|x+1|), तो (f^{-1}({4})) कौन-सा समुच्चय है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ({-5,3})({-5,3})
Step 1: To find the preimage, solve (|x+1|=4). Step 2: This gives (x+1=4) or (x+1=-4). Step 3: Thus (x=3) or (x=-5), so the preimage is ({-5,3}).चरण 1: पूर्वछवि के लिए (|x+1|=4) हल करें। चरण 2: इससे (x+1=4) या (x+1=-4) मिलता है। चरण 3: इसलिए (x=3) या (x=-5), अतः पूर्वछवि ({-5,3}) है।
