यदि (f(x)=x+1), (g(x)=x-1) और (h(x)=x-2) हों, तो ((f+g+h)(x)) क्या होगा?

If (f(x)=x+1), (g(x)=x-1), and (h(x)=x-2), what is ((f+g+h)(x))?

Explanation opens after your attempt
Correct Answer

A. \(x^2+2x\)

Step 1

Concept

((f+g+h)(x)=(x+1)+(x-1)+x-2=x-2+2x). The constants (1) and (-1) cancel out.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+2x\). ((f+g+h)(x)=(x+1)+(x-1)+x-2=x-2+2x). The constants (1) and (-1) cancel out.

Step 3

Exam Tip

((f+g+h)(x)=(x+1)+(x-1)+x-2=x-2+2x)। constants (1) और (-1) cancel हो जाते हैं।
