@@mathoutloud I just used method I saw on a similar question from a Oxford maths question a few years ago, makes sense as easier than integrating two functions.
@cotf-s1n thanks! It’s probably good to be able to do things in general but also recognize when a specific problem will allow for simplifications. Usually in my videos I just go with whatever idea comes to me first unless I think some extra thought will allow for something simpler.
@@mathoutloud These multiple choice questions often appear in tests with extremely harsh time constraints. So it is very valuable to not only understand the answer but it is even more important to rake up time-saves on these easy questions to have breathing room
Hi, I just graphed y= |x+1|, you just end up with two triangles, then using those bounds and use Area=½ b.h for each triangle.
Almost certainly faster than me. I’m a creature of habit, and in this case a habit of over complicating things.

@@mathoutloud the method u used is more general and I prefer it since u can't always get nice and easy shapes. Nice video.
