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. Well, negative one squared is just one, so this is going to be equal to six. So we actually know what all of these values are now. We know, so first we want to figure out f prime of negative one.
