    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.

      @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.
