If the range of the function `y=(x-1)/(x+1)` on the interval `0lexle4` be `[a,b]` then the value of `5b-2a=`

Explanation

To find the value of \(5b - 2a\) for the function \(y = \frac{x-1}{x+1}\) on the interval \(0 \leq x \leq 4\), we will follow these steps:

### Step 1: Analyze the function
The function given is:
\[ y = \frac{x-1}{x+1} \]
We need to find the range of this function for \(x\) in the interval \([0, 4]\).
