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. When x is equal to negative three, our function is at zero. So f of negative three is just zero. So it's just two plus zero, which is equal to two.
