That's just going to be one. And if you view this as x to the first power, we're just bringing the one out front and decrementing the one. So we have one times x to the zero power, which is just one. And then the derivative of a constant here is just going to be zero. So this is our derivative of f, and if we want to evaluate it at one, f prime of one is going to be three times one squared, which is just three, minus 12 times one, so it's just minus 12, and then we have plus one. So this is three minus 12 is negative nine, and negative nine plus one is equal to negative eight. So we know the slope right over here is a slope of negative eight.
