So it's 3 plus delta x up there. So what's the y value going to be? Well, whatever x value is, it's on the curve, it's going to be that squared. So it's going to be, this is going to be the point 3 plus delta x squared. So let's figure out the slope of this secant line. Let me zoom in a little bit because that might help. So if I zoom in on just this part of the curve, it might look like that.
