So let's actually just, let's just, so we want the equation of the tangent line when x is equal to one. So let's just first of all evaluate f of one. So f of one is equal to one to the third power, which is one, minus six times one squared, so it's just minus six, and then plus one, plus one, minus five. So this is equal to what? Two minus 11, which is equal to negative nine. And that looks about right. That looks like about negative nine right over there.
