1 fourth times 8 pi, so this all simplifies to 2 pi. So g of negative 4 is equal to negative 8 minus 2 pi. So clearly a negative number here, more negative than negative 8. So let's try the other bounds. Let's see what g of positive 3 is. Let's see what g of positive, I'll do it over here so I have more space. So g of positive 3, when x is equal to 3, that, we go back to our definition, that is 2 times 3, plus the integral from 0 to 3, f of t dt.
