If (f(x)=|x-2|) and (g(x)=x-2), on which interval is (f-g) equal to (0)?यदि (f(x)=|x-2|) और (g(x)=x-2) हैं, तो (f-g) किस अंतराल पर (0) होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( [2,\infty) )( [2,\infty) )
When (x\ge2), (|x-2|=x-2), so (f-g=0). For modulus functions, making cases is the safest method.जब (x\ge2), तब (|x-2|=x-2), इसलिए (f-g=0)। मापांक वाले फलन में केस बनाना सबसे सुरक्षित तरीका है।
