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