I think i would start by graphing f of x, because if you look at the problem at x is one, we have a hole here, because on the left side it's just a horizontal line, i'm going to make that look at one, but then to the right it's just a diagonal line going up one over one.
00:17
So, with that being f, i'd probably even write out the limit as x approaches, oh, well a bunch of them change things.
00:32
Okay, well let's just leave that graph, and then we might, might need to look at some different things.
00:38
So, then looking at g of x, at x equals two is the big deal, x equals two.
00:46
We have a hole at two, because it's going up one over one, just a diagonal line in here, but at x equals two it goes up to three as a closed dot.
00:56
So, as i ask you to evaluate the limit, this is part a, as x approaches two of f of x plus g of x, just do each individual limit.
01:09
So, at x is two on this one, that's why i wasn't really prepared for it, but the y value is two on both sides, and then at g of x the y value is also two on both sides.
01:20
We don't do the defined value, we do what it's approaching on both sides...
