\]
Solution
Solution Steps
To find the first and second derivatives of the function \( y = 3x + 6 \), we will use basic differentiation rules. The first derivative of a linear function \( ax + b \) is simply the coefficient \( a \). The second derivative of a constant or linear function is zero.
Step 1: Identify the Function
The given function is \( y = 3x + 6 \).
Step 2: Calculate the First Derivative
To find the first derivative of \( y \) with respect to \( x \), we differentiate the function:
\[
\frac{dy}{dx} = \frac{d}{dx}(3x + 6) = 3
\]
Step 3: Calculate the Second Derivative
To find the second derivative, we differentiate the first derivative:
\[
\frac{d^2y}{dx^2} = \frac{d}{dx}(3) = 0
\]
