F(x)= dU/dx, du= F(x)dx => dU= (ax + bx²)dx. Integrating we get U= ax²/2 + bx³/3. At x = 1m we have U= a/2 + b/3.....(1). At x = 3m we have U= 9a/2 + 27b/3.....(2). Subtracting we hv U= 8a/2 + 26b/3. Solving we get 6U= 24a + 52b. Substituting the values
I can say that the answer is b, because it is not used for permanent storage
