The correct Answer is:
To find the first and second derivatives of the function \( y = 6x^2 - 10x \) with respect to \( x \), we will follow these steps: ### Step 1: Find the First Derivative The first derivative of a function \( y \) with respect to \( x \) is denoted as \( \frac{dy}{dx} \). 1. Start with the function: \[ y = 6x^2 - 10x \] 2. Differentiate each term: - For the term \( 6x^2 \): - Use the power rule: \( \frac{d}{dx}(x^n) = nx^{n-1} \). - Here, \( n = 2 \), so: \[ \frac{d}{dx}(6x^2) = 6 \cdot 2x^{2-1} = 12x \] - For the term \( -10x \): - Again, use the power rule where \( n = 1 \): \[ \frac{d}{dx}(-10x) = -10 \cdot 1x^{1-1} = -10 \] 3. Combine the results: \[ \frac{dy}{dx} = 12x - 10 \] ### Step 2: Find the Second Derivative The second derivative is denoted as \( \frac{d^2y}{dx^2} \). 1. Start with the first derivative: \[ \frac{dy}{dx} = 12x - 10 \] 2. Differentiate the first derivative: - For the term \( 12x \): \[ \frac{d}{dx}(12x) = 12 \] - For the constant term \( -10 \): \[ \frac{d}{dx}(-10) = 0 \] 3. Combine the results: \[ \frac{d^2y}{dx^2} = 12 \] ### Final Results - The first derivative \( \frac{dy}{dx} = 12x - 10 \) - The second derivative \( \frac{d^2y}{dx^2} = 12 \)
