Find the slope of tangent of the curve y =4x^2 at the point (-1,4).

Explanation

To find the slope of the tangent to the curve \( y = 4x^2 \) at the point \((-1, 4)\), we will follow these steps:

### Step 1: Differentiate the function
We start with the given function:
\[ y = 4x^2 \]
To find the slope of the tangent, we need to differentiate \( y \) with respect to \( x \).
