यदि \(f:\mathbb{R}\to\mathbb{R}\), (f(x)=\frac{3x-2}{5}), तो (f) के बारे में सही उत्तर क्या है?

If \(f:\mathbb{R}\to\mathbb{R}\), (f(x)=\frac{3x-2}{5}), what is the correct answer about (f)?

Explanation opens after your attempt
Correct Answer

A. एकैकी हैIt is one-one

Step 1

Concept

Write (f(a)=f(b)).

Step 2

Why this answer is correct

From \(\frac{3a-2}{5}=\frac{3b-2}{5}\), we get (3a-2=3b-2), so (a=b).

Step 3

Exam Tip

A linear function written as a fraction is also one-one if the coefficient of (x) is non-zero. चरण 1: (f(a)=f(b)) लिखें। चरण 2: \(\frac{3a-2}{5}=\frac{3b-2}{5}\) से (3a-2=3b-2) और (a=b)। चरण 3: भिन्न में लिखा रैखिक फलन भी एकैकी होता है यदि (x) का गुणांक शून्य नहीं हो।
