I divided it up into two regions (-1 to 0 -> A1 and 0 to 8 -> A2). I found A2 to be 12 and A1 to be |-3/4|. My teacher worked the problem on the review sheet and she got |-1| for A1. How is this possible?!
We both have the same equation:
A1 = (3/4)x^(4/3) evaluated from 0 to -1. Obviously x=0 will yield 0, and when I plug in -1 I get -3/4! Am I just completely missing something?
For the total area, I get 12.75 units, and my teacher got 13.
