Answer

\boxed{C(x) = \frac{4}{3}x^3 - \frac{5}{2}x^2 + 2000}

Steps

Step 1 :The given derivative is \(C^{\prime}(x)=4 x^{2}-5 x\). To find the antiderivative, we integrate \(C^{\prime}(x)\) with respect to \(x\).

Step 2 :The antiderivative of \(C^{\prime}(x)\) is given by \(C(x) = \int C^{\prime}(x) dx = \int (4x^2 - 5x) dx\).

Step 3 :Using the power rule for integration, we get \(C(x) = \frac{4}{3}x^3 - \frac{5}{2}x^2 + C\), where \(C\) is the constant of integration.

Step 4 :We are given that \(C(0) = 2000\). Substituting these values into the equation, we get \(2000 = \frac{4}{3}(0)^3 - \frac{5}{2}(0)^2 + C\).

Step 5 :Solving for \(C\), we get \(C = 2000\).

Step 6 :Therefore, the particular antiderivative of \(C^{\prime}(x)\) that satisfies the given condition is \(C(x) = \frac{4}{3}x^3 - \frac{5}{2}x^2 + 2000\).

Step 7 :\boxed{C(x) = \frac{4}{3}x^3 - \frac{5}{2}x^2 + 2000}
