Let \(f(x)\)be a function satisfying \(f^{\prime}(\mathbf{x})=f(\mathbf{x})\) with \(f(0)=1\) and \(g(x)\) be a function that satisfies \(f(x)+g(x)=x^{2}\). Then the value of the integral \(\int_{0}^{1} f(x) g(x) d x \text { is }\)
  1. \(e-\frac{e^{2}}{2}-\frac{5}{2}\)
  2. \(e+\frac{e^{2}}{2}-\frac{3}{2}\)
  3. \(e-\frac{e^{2}}{2}-\frac{3}{2}\)
  4. \(e+\frac{e^{2}}{2}+\frac{5}{2}\)

Answer

(C) e- e^ 2 2 - 3 2
