Best ResponseYou've already chosen the best response.0think if we have the integral of x^2 from 2..2 =16/3 if we have the integral of x^2 from 0..2=8/3 if we have the integral of x^2 from 2..0=8/3 so lets think about your problem

Best ResponseYou've already chosen the best response.0Since it's even, the integral from 7 to 1 is the same as the integral from 1 to 7.

Best ResponseYou've already chosen the best response.0think about x^2 from 0..1, its 1/3 from 0..7. its 7^3/3 from 1..7 its 7^3/3+1/3

Best ResponseYou've already chosen the best response.0if you see what happen to x^2, you can see what will happen here

Best ResponseYou've already chosen the best response.0Oh sorry I was figuring out the problem but you you would just flip the parameters and change the signs around right!

Best ResponseYou've already chosen the best response.0from 7..1 of x^2 its 1/3+7^3/3 to get this without integrating we just do 7^3/31/3 which is the integral from 0..7 minus the integral from 0..1

Best ResponseYou've already chosen the best response.0Okay I understand! So the integral from 1 to 0 f(x) dx = 5 changes to the integral from 0 to 1 f(x) dx = 5 and you add it to the integral from 0 to 7 which is 1 making 4
