Differentiate each function by applying the basic rules of differentiation
`x-(1)/(x)`

Explanation

To differentiate the function \( y = x - \frac{1}{x} \), we will apply the basic rules of differentiation step by step.

### Step 1: Rewrite the function
First, we express the function in a more convenient form for differentiation:
\[ y = x - \frac{1}{x} \]
This can be rewritten as:
