If `f(x)=2x-3`, the inverse of `f,f^(-1)` could be represented by

A

`f^(-1)(x)=3x-2`

B

`f^(-1)(x)=(1)/(2x-3)`

C

`f^(-1)(x)=(x-2)/(3)`

D

`f^(-1)(x)=(x+3)/(2)`

The correct Answer is:
To find the inverse of the function \( f(x) = 2x - 3 \), we will follow these steps: ### Step-by-Step Solution: 1. **Replace \( f(x) \) with \( y \)**: \[ y = 2x - 3 \] 2. **Isolate \( x \)**: - First, add 3 to both sides: \[ y + 3 = 2x \] - Next, divide both sides by 2: \[ x = \frac{y + 3}{2} \] 3. **Express the inverse function**: - We can now express the inverse function \( f^{-1}(x) \) by replacing \( y \) with \( x \): \[ f^{-1}(x) = \frac{x + 3}{2} \] ### Final Answer: Thus, the inverse of the function \( f(x) = 2x - 3 \) is: \[ f^{-1}(x) = \frac{x + 3}{2} \]
