The correct Answer is:
To determine whether the statement "If \( f(x) = x^2 - 3x + 1 \), then the derivative of \( f(x) \) at \( x = 2 \), \( f'(2) = 1 \)" is true or false, we will follow these steps: ### Step 1: Find the derivative of \( f(x) \) The function given is: \[ f(x) = x^2 - 3x + 1 \] To find the derivative \( f'(x) \), we differentiate \( f(x) \) with respect to \( x \): \[ f'(x) = \frac{d}{dx}(x^2) - \frac{d}{dx}(3x) + \frac{d}{dx}(1) \] Calculating each term: - The derivative of \( x^2 \) is \( 2x \). - The derivative of \( 3x \) is \( 3 \). - The derivative of a constant \( 1 \) is \( 0 \). Thus, combining these results, we have: \[ f'(x) = 2x - 3 \] ### Step 2: Evaluate the derivative at \( x = 2 \) Now we need to find \( f'(2) \): \[ f'(2) = 2(2) - 3 \] Calculating this gives: \[ f'(2) = 4 - 3 = 1 \] ### Step 3: Compare with the given statement The statement claims that \( f'(2) = 1 \). Since we calculated \( f'(2) \) and found it to be \( 1 \), the statement is indeed true. ### Conclusion Thus, the statement is **True**. ---
