Draw the graph of the function `f(x) = x-|x2-x| -1 le x le 1`, where `[*]` denotes the greatest integer function. Find the points of discontinuity and non-differentiability.

Explanation

To solve the problem of drawing the graph of the function \( f(x) = x - |x^2 - x| \) for \( -1 \leq x \leq 1 \) and finding points of discontinuity and non-differentiability, we can follow these steps:

### Step 1: Understand the function
The function involves an absolute value, so we need to analyze the expression \( |x^2 - x| \). This expression can be rewritten based on the sign of \( x^2 - x \).

### Step 2: Determine the critical points
Set the expression inside the absolute value to zero:
\[
