Let's keep doing this. If I go right over here, when x is equal to four, this point is four comma natural log of four. But the slope of the tangent line here looks pretty close to 1 4. And if you accept this, it is exactly 1 4. And you could even go to values less than one. Right over here, when x is equal to 1 1, one over 1 1, the slope should be two. And it does indeed, let me do this in a slightly different color, it does indeed look like the slope is two over there.
