So this is equal to negative one. And then last but not least, if we want to find g prime of negative one, we just have to take the derivative of this. So g prime of x, actually, let me just rewrite g of x. g of x, one over x is just the same thing as x to the negative one. So we're gonna use a power rule to figure out g prime of x is equal to, bring that exponent out front, negative one times x to the, and then decrement the exponent negative two power. So g prime of negative one, of negative one is equal to negative one times negative one to the negative two power. And that's just the same thing as negative one over negative one squared. This is one, so this is just all going to evaluate to negative one.
