यदि (f(x)=2x-2-1) हो, तो ((3f)(x)) क्या है?

If (f(x)=2x-2-1), what is ((3f)(x))?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

((3f)(x)=3f(x)=3\(2x^2-1\)=6x-2-3). Multiply the scalar by the whole function.

Step 2

Why this answer is correct

The correct answer is A. \(6x^2-3\). ((3f)(x)=3f(x)=3\(2x^2-1\)=6x-2-3). Multiply the scalar by the whole function.

Step 3

Exam Tip

((3f)(x)=3f(x)=3\(2x^2-1\)=6x-2-3)। scalar को पूरी function से multiply करें।
