H prime of three is going to be equal to one over, one over, one over g prime of h of three, which I'm guessing that they have given us. So h of three, when x is three, h is four. So that is h of three there. So h of three is four. So now we just have to figure out g prime of four. Well lucky for us, they have given us, when x is equal to four, g prime, g prime is equal to 1 1 2. So g prime of four is equal to 1 1 2.
