Best ResponseYou've already chosen the best response.0you need to have bounds; if the two cross paths you can use that, but an interval is usually stated.

Best ResponseYou've already chosen the best response.0i found the bounds to be sqrt(5) and sqrt(5) but when i put them into the integral equation, i get some crazy number that isn't right...

Best ResponseYou've already chosen the best response.0right now i have [(1/3)x^3+x][11x(1/3)x^3] for the two integrals

Best ResponseYou've already chosen the best response.0instead of integrating from sqrt(5) to sqrt(5), integrate from 0 to sqrt(5) and then double your answer this is due to symmetry of parabolas

Best ResponseYou've already chosen the best response.0you have already done the integration just evaluate at sqrt(5) into what you posted above
