यदि (f(x)=2x), (g(x)=x+3) और (h(x)=x-1) हों, तो ((f+g-h)(x)) क्या होगा?

If (f(x)=2x), (g(x)=x+3), and (h(x)=x-1), what is ((f+g-h)(x))?

Explanation opens after your attempt
Correct Answer

A. (2x+4)

Step 1

Concept

(2x+(x+3)-(x-1)=2x+4). Even with three functions, combining like terms is the key step.

Step 2

Why this answer is correct

The correct answer is A. (2x+4). (2x+(x+3)-(x-1)=2x+4). Even with three functions, combining like terms is the key step.

Step 3

Exam Tip

(2x+(x+3)-(x-1)=2x+4)। तीन फलनों में भी समान पद जोड़ना ही मुख्य काम है।
