1. The problem statement, all variables and given/known data Given that the integral of g(u)du on the interval [0.2] is 12, what is g(2-u)du on the interval [0,2] 2. Relevant equations f on [a,b] is F(b) - F(a). 3. The attempt at a solution Switching from positive to negative t flips the limits to [2,0]. This would yield -12 instead of 12. F(2) on 0,2 would just be 4. The answer of -8, however is not correct. Have I violated order of operations or am I missing a concept?
