यदि (f(x)=x-3) और (g(x)=x+5) हों, तो ((fg)(0)) का मान क्या है?

If (f(x)=x-3) and (g(x)=x+5), what is the value of ((fg)(0))?

Explanation opens after your attempt
Correct Answer

A. (-15)

Step 1

Concept

(f(0)=-3) and (g(0)=5), so the product is (-15). When (x=0), constant terms remain.

Step 2

Why this answer is correct

The correct answer is A. (-15). (f(0)=-3) and (g(0)=5), so the product is (-15). When (x=0), constant terms remain.

Step 3

Exam Tip

(f(0)=-3) और (g(0)=5), इसलिए गुणनफल (-15) है। (x=0) रखने पर स्थिर पद बचते हैं।
