Beyond the Answer
To check if \( y = x^3 - 5x + 2 \) satisfies the differential equation \( \frac{dy}{dx} = 3x^2 - 5 \), we first need to find the derivative of \( y \) with respect to \( x \). Calculating the derivative: \[ \frac{dy}{dx} = \frac{d}{dx}(x^3 - 5x + 2) \] Using the power rule and the linearity of derivatives, we get: \[ \frac{dy}{dx} = 3x^2 - 5 \] Now, we compare this result with the right side of the differential equation: The derivative we found, \( \frac{dy}{dx} = 3x^2 - 5 \), is exactly the same as the right side of the given differential equation \( \frac{dy}{dx} = 3x^2 - 5 \). Thus, we can conclude that the function \( y = x^3 - 5x + 2 \) does indeed satisfy the differential equation \( \frac{dy}{dx} = 3x^2 - 5 \).
