Differentiate each function by applying the basic rules of differentiation
`3x^(-2)-7x^(-1)+6`

Explanation

To differentiate the function \( y = 3x^{-2} - 7x^{-1} + 6 \), we will apply the basic rules of differentiation step by step.

### Step 1: Identify the function to differentiate
Let \( y = 3x^{-2} - 7x^{-1} + 6 \).

### Step 2: Differentiate each term
We will differentiate each term separately using the power rule of differentiation, which states that if \( f(x) = ax^n \), then \( f'(x) = n \cdot ax^{n-1} \).
