We don't know if it's even gonna be a good estimate. It's just going to be a best estimate. So what we generally do when we just have some data around a point is let's use the data points that are closest to that point and find slopes of secant lines pretty close around that point. And that's going to give us our best estimate for the slope of the tangent line. So what points do we have near F of four or near the point four comma F of four? Well, they give us what F is equal to when x is equal to three. They give us this point right over here.
