To find the minimum value of the function \( f(x) = x^2 + \frac{250}{x} \), we will follow these steps: ### Step 1: Find the first derivative We start by differentiating the function with respect to \( x \): \[ f'(x) = \frac{d}{dx}(x^2) + \frac{d}{dx}\left(\frac{250}{x}\right) \] Using the power rule and the quotient rule, we have: ...
