And so f prime of two, right this way, f prime of two is going to be equal to two times two, two times two, minus whatever y is when x is equal to two. Well, do we know what y is when x equals to two? Sure, they tell us right over here. Y is equal to f of x. So when x is equal to two, when x is equal to two, y is equal to three. So two times two minus three, and so this is going to be equal to four minus three is equal to one. And so since the derivative at two is not zero, this is not going to be a minimum, a relative minimum, or a relative maximum.
