On the derivative, the derivative is decreasing, which means the slope of our tangent line of our original function is decreasing, and we saw that. Notice, while the derivative is decreasing right over here, our slope will be decreasing. Our slope is positive, our slope is positive, but decreasing, then it becomes negative, but decreasing all the way until this point, which is at x equals negative one. So let's do that again. So our slope is positive and decreasing, and then right over about there, right over here, our slope keeps decreasing, but then it actually turns negative, and it keeps decreasing all the way until x equals negative one. And then our slope begins increasing again. So the derivative begins increasing, which means the slope of our tangent line of our original function begins increasing.
