have any idea?

anonymous · Answer

well.... 
f(7) - f(3) is what the integral is.. but i don't know what that equals to.. 
do you just take the integral of the other side as well?
so it's:
f(7) - 11 = 20x?

just you can't do that cuz there are two unknowns.

Hey @dpaInc  will you please tell you did you zoom that letters that day??
And how to show cancelling of each term and if I want to show the factor by which I am cancelling that then can you please tell me how we do it??

anonymous · Answer

yes.. you're basically using the FTC.... $\large \int_a^b f'(t)dt=f(b)-f(a) $

anonymous · Answer

since f(7) - f(3) = 20, and f(3)=11... you can find f(7)

oh. so it is just plug in!
haha, thanks! i just needed to see that..
