Find the derivative of `x^2-2`at `x = 10`.

Explanation

To find the derivative of the function \( f(x) = x^2 - 2 \) at \( x = 10 \), we will follow these steps:

### Step 1: Differentiate the function
We start by differentiating the function \( f(x) = x^2 - 2 \) with respect to \( x \).

Using the power rule of differentiation, which states that if \( f(x) = x^n \), then \( f'(x) = n \cdot x^{n-1} \), we can differentiate \( x^2 \):

\[
