And if you couldn't figure it out the first time around, try to pause the video again, and now that we've figured out g of four, try to figure out what g of eight is. Well g of eight is, one way to think about it, it's going to be that minus that area, and then we're going to add, and then we're going to figure out the area, and then we're going to have two more areas to think about. We're going to go all the way to eight, so actually let me draw the line there. So we're going to have to think about, we're going to think about this whole area now, this whole area now, and then we're going to think about this one. So we could write, this is going to be equal to the integral between, let me do that purple color. So it's going to be this integral, which is the integral between negative t equals negative three and zero, g of t dt, plus this entire yellow region right now, the part that we looked at before, plus this part over here, so I'll just write that as plus the definite integral between t is equal to zero and six, g of t dt, and then finally, plus the definite integral between t is equal to six and t is equal to eight, g of t dt. Now, we already know that this first one evaluates to 4.5, so that one is 4.5.
