यदि (f(x)=x+3) और (g(x)=2x-6) हों, तो ((fg)(0)) क्या है?

If (f(x)=x+3) and (g(x)=2x-6), what is ((fg)(0))?

Explanation opens after your attempt
Correct Answer

A. (-18)

Step 1

Concept

(f(0)=3) and (g(0)=-6), so ((fg)(0)=3\cdot(-6)=-18). Do not make a sign error in multiplication.

Step 2

Why this answer is correct

The correct answer is A. (-18). (f(0)=3) and (g(0)=-6), so ((fg)(0)=3\cdot(-6)=-18). Do not make a sign error in multiplication.

Step 3

Exam Tip

(f(0)=3) और (g(0)=-6), इसलिए ((fg)(0)=3\cdot(-6)=-18)। sign multiplication में गलती न करें।
