All right, all of that over, g of negative one squared, g of negative one squared. Now, can we figure out what f prime of negative one, f of negative one, g of negative one, and g prime of negative one, what they are? Well, some of them they tell us outright. They tell us f and f prime at negative one, and for g, we can actually solve for those. So let's see, if this is, well, let's just first evaluate g of negative one. g of negative one is going to be two times negative one to the third power. Well, negative one to the third power is just negative one times two, so this is negative two, and g prime of x, I'll do it here, g prime of x, which use the power rule, bring that three out front, three times two is six, x, decrement that exponent, three minus one is two, and so g prime of negative one is equal to six times negative one squared.
