So we can visualize that. So this is x equaling one right over here. This is the value of the function when x is equal to one, right over there. And then the tangent line looks something like, will look something like, oh no, I can do a better job than that. It's going to look something like that. And what we want to do is find the equation, the equation of that line. And if you are inspired, I encourage you to be, pause the video and try to work it out.
