Question 1/1 Medium Mathematics Relations and Functions One-one function Class 12 Level 24

यदि \(f:\mathbb{R}\to\mathbb{R}\) और (f(x)=4x+4) है, तो (f(a)=f(b)) से क्या निष्कर्ष निकलेगा?

If \(f:\mathbb{R}\to\mathbb{R}\) and (f(x)=4x+4), what conclusion follows from (f(a)=f(b))?

Explanation opens after your attempt
Correct Answer

A. (a=b)

Step 1

Concept

Writing (f(a)=f(b)) gives (4a+4=4b+4).

Step 2

Why this answer is correct

Subtracting (4) and dividing by (4) gives (a=b).

Step 3

Exam Tip

This is the standard method to prove one-one nature. चरण 1: (f(a)=f(b)) लिखने पर (4a+4=4b+4) मिलता है। चरण 2: दोनों ओर से (4) घटाने और (4) से भाग देने पर (a=b)। चरण 3: यही प्रक्रिया एकैकीपन सिद्ध करने की मानक विधि है।
