Mathematics Answer, Explanation and Revision Hints
यदि (f(x)=x-2-1) और (g(x)=x+1), तो (\(f\circ g\)(2)) का मान क्या है? / If (f(x)=x-2-1) and (g(x)=x+1), what is the value of (\(f\circ g\)(2))?
Correct Answer: C. (8). Explanation: चरण 1: पहले (g(2)=2+1=3) निकालें। चरण 2: अब (f(g(2))=f(3)=32-1=8)। चरण 3: संयोजन में हमेशा भीतर वाले फलन को पहले हल करें। / Step 1: First find (g(2)=2+1=3). Step 2: Now (f(g(2))=f(3)=32-1=8). Step 3: In composition, always evaluate the inner function first.
