That is just going to be f of x. So that is g prime of x. We did this second part right over there. That is g prime of x. And then we need to evaluate it at negative three. So g prime of negative three, g prime of negative three is going to be equal to two plus f of negative three, which is equal to two plus, and let's look at our, let's see what f of negative three is. This is our function definition.
