यदि (f(x)=x+1) और (g(x)=x-2) हैं, तो ((fg)(x)) का घात क्या है?
If (f(x)=x+1) and (g(x)=x-2), what is the degree of ((fg)(x))?
Explanation opens after your attempt
A. (3)
Concept
((fg)(x)=(x+1)x-2=x-3+x-2), so the degree is (3). In polynomial products, check the highest power.
Why this answer is correct
The correct answer is A. (3). ((fg)(x)=(x+1)x-2=x-3+x-2), so the degree is (3). In polynomial products, check the highest power.
Exam Tip
((fg)(x)=(x+1)x-2=x-3+x-2), इसलिए घात (3) है। बहुपद गुणा में उच्चतम घात देखें।
