यदि (f(x)=\frac{2x+1}{3}), तो (f^{-1}(x)) क्या होगा?

If (f(x)=\frac{2x+1}{3}), what is (f^{-1}(x))?

Explanation opens after your attempt
Correct Answer

A. \(\frac{3x-1}{2}\)

Step 1

Concept

Write \(y=\frac{2x+1}{3}\).

Step 2

Why this answer is correct

Then (3y=2x+1), so \(x=\frac{3y-1}{2}\).

Step 3

Exam Tip

Replacing (y) by (x), (f^{-1}(x)=\frac{3x-1}{2}). चरण 1: \(y=\frac{2x+1}{3}\) लिखें। चरण 2: (3y=2x+1), इसलिए \(x=\frac{3y-1}{2}\)। चरण 3: (y) को (x) से बदलने पर (f^{-1}(x)=\frac{3x-1}{2})।
