If (f(x)=2x+1) and (g(x)=x^2-1), what is the value of ((g\circ f)(2))?यदि (f(x)=2x+1) और (g(x)=x^2-1), तो ((g\circ f)(2)) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (24)(24)
Step 1: ((g\circ f)(2)=g(f(2))). Step 2: (f(2)=2\cdot2+1=5). Step 3: (g(5)=5^2-1=24), so the answer is (24).चरण 1: ((g\circ f)(2)=g(f(2)))। चरण 2: (f(2)=2\cdot2+1=5)। चरण 3: (g(5)=5^2-1=24), इसलिए उत्तर (24) है।
