Question

If: "1∫9 f(x)dx = -1" & "7∫9 f( x)dx = 5", then does "1∫7 f(x)dx = -6" ?

*I got to this answer referencing the "Reversing Limits of Integration Rule" and the "Integral Addition Rule"... I am not sure if this is technically a legitimate way to apply those rules, or the right process to navigate the problem by... I just kind of need someone who can navigate these problems well to verify if I have a proper understanding here.

Any and all help/ advice is greatly appreciated! :)

Answer 1

Yep that is correct
