Well, here, let me do it in another color, the slope of the tangent line sure looks pretty close, sure looks pretty close to two. What about, what about when e to the x is equal to 1 1⁄2? So that's happening right about here. Well, it sure looks like the slope of the tangent line is about 1 1⁄2. We could try, what happens when e to the x is equal to five? Well, the slope of the tangent line here sure does look pretty close, sure does look pretty close to five. And so, just eyeballing it, is it the case that the slope of the tangent line of e to the x is the same thing, is e to the x?
