यदि (f(x)=3) और (g(x)=x-2-2x) हों, तो ((fg)(x)) क्या होगा?

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

Explanation opens after your attempt
Correct Answer

A. \(3x^2-6x\)

Step 1

Concept

The constant function (3) multiplies the whole (g(x)). Thus ((fg)(x)=3\(x^2-2x\)=3x-2-6x).

Step 2

Why this answer is correct

The correct answer is A. \(3x^2-6x\). The constant function (3) multiplies the whole (g(x)). Thus ((fg)(x)=3\(x^2-2x\)=3x-2-6x).

Step 3

Exam Tip

स्थिर फलन (3) पूरे (g(x)) से गुणा होगा। इसलिए ((fg)(x)=3\(x^2-2x\)=3x-2-6x)।
