this problem G of X is to x and h of X is X squared plus four and it wants us evaluate hoh at two. So we're gonna do is we're gonna plug in this expose for into this X right here. It's a little weird, but so this is X squared plus four. Then I have to square this square. This plus four ISS problem. It's probably easier just thio plug in my two right here instead of simplifying it out. So we're gonna do so. I have two squared plus four squared plus four. So gonna do inside the princess first. So too screwed up. Here is four plus four squared plus four, four plus four Here is eight. So I have eight squared plus four eight squared is 64 plus four losing with 68.
