Best ResponseYou've already chosen the best response.0\[if \left(\begin{matrix}8x^2 for 2\le x \le2 \\ x^2 else where,\end{matrix}\right) then \int\limits_{1}^{3}f(x) dx is a number \between \]

Best ResponseYou've already chosen the best response.0is a number between?* would you like to know the choices?

Best ResponseYou've already chosen the best response.1what 8 do yu want us to ignore? 8x^2? this should be part of the funtion

Best ResponseYou've already chosen the best response.0i am talking about the title of the question. that is what you should ignore

Best ResponseYou've already chosen the best response.0\[f(x) = \left\{\begin{array}{rcc} 8x^2 & \text{if} & 2\leq x\leq 2\\ x^2& \text{otherwise} & \end{array} \right. \] just seeing if i could do it, ignore me

Best ResponseYou've already chosen the best response.1alright you just do some linearity here see where you should integrate 8x^2 and x^2

Best ResponseYou've already chosen the best response.1as you can see from 1<x<2 you can integrate 8x^2

Best ResponseYou've already chosen the best response.1the rest 2 to 3 you integrate x^2

Best ResponseYou've already chosen the best response.1\[\int_{1}^{3}f(x)dx=\int_{1}^{2}f(x)dx+\int_{2}^{3}f(x)dx\] \[\int_{1}^{2}(8x^2)dx+\int_{2}^{3}x^2dx\]

Best ResponseYou've already chosen the best response.0The choices were a) 0 and 8 b) 8 and 16 c) 16 and 24 d) 24 and 32 e) 32 and 40

Best ResponseYou've already chosen the best response.1hmm i see so they separated it you just do those two integral separately

Best ResponseYou've already chosen the best response.0sorry, i will do that now

Best ResponseYou've already chosen the best response.1now i got what is those btw mean we need to add those two integrals and see the solution lies btw what two points

Best ResponseYou've already chosen the best response.1i found 21 +19/3 =82/3 which lies 24<82/3<32

xapproachesinfinity

Best ResponseYou've already chosen the best response.1go with what we found in the first time and add the other integral

Best ResponseYou've already chosen the best response.1hmm why 19/3?

Best ResponseYou've already chosen the best response.1\[\int_{2}^{3}x^2ds=\frac{x^3}{3}=19/3\]

Best ResponseYou've already chosen the best response.0Instead of getting the sum of both integrals, I decided to do the difference.
