Best ResponseYou've already chosen the best response.1ah... try taking the antiderivative.... then f(b)f(a) which is f(3x) f(1) and then evaluate when x = 1?!?!?!!?!?!!!!!!!!!!!!!!!!!!!!!!!!!! this is one strange question

Best ResponseYou've already chosen the best response.1because whenever I see the integral sign... it's always antiderivative.

Best ResponseYou've already chosen the best response.2Hey sorry I was away, yeah sure just send me a message of what exactly you want. since F'(x) = f(x) we have\[F'(x) = \int\limits_{1}^{3x} \ln(t^2) dt\] \[F'(x) = \ln(9x^2)  \ln(1)\] F''(x) = f'(x) \[F''(x) = \frac{ 2 }{ x }\] \[F''(1) = 2\] so this is what you did?

Best ResponseYou've already chosen the best response.1so somehow the answer choices and whatever you guys did don't match... :/ ~_O! either wrong problem screenshot or wrong answer choices?!!!!!

Astrophysics

Best ResponseYou've already chosen the best response.2\[\frac{ d }{ dx } \int\limits_{1}^{3x} \ln(t^2) dt = \ln(3x)\] see it basically just cancels out the integral you get what you initially started with, but I don't really trust this integral itself...

Astrophysics

Best ResponseYou've already chosen the best response.2Ah wait let me see...F'(x) = f(x) \[F'(x) = \int\limits_{0}^{3x} \ln(t^2) dt = \ln(9x^2)\ln(1) \] \[F'(x) = \ln(9x^2) \times (3x)' = 3\ln(9x^2) \] I found the mistake...we're suppose to take the derivative of 3x as well..totally missed that part...ok so we have now F''(x) = f'(x) \[F''(x) = \frac{ 6 }{ x } \implies f''(1)= 6\]

Best ResponseYou've already chosen the best response.1the variable on f(b) I remember using FTC part 1 all the time on that one... you have to substitute it into the equation (that ln t^2) and then take the derivative of 3x as well

Astrophysics
