1. The problem statement, all variables and given/known data The integral of f(x) from 0 to 1 is 3, and the integral of f(x) from 1 to 3 is -2. What is the integral of f(x) from -3 to 3? 2. Relevant equations FTC. 3. The attempt at a solution From the equations given I know: F(1) - F(0) = 3, and F(3) - F(1) = -2. How do I find F(3) - F(-3)? I don't know if the function is symmetrical so that doesn't help. The closest I can do is solve for F(3). But where do I get F(-3)?
