drawing – How to draw a function with a particular tangent line at a specific point?

I would like to draw a function (x / x ^ 2 + 1), and at a certain point, I would like to draw a point with the tangent line at that specific point.

what i have tried is as follows:

Ground[{function[x], a function & # 39;[x]}, {x, -5, 5}, AxesLabel -> {x, y} LabelStyle -> Direction[Black, Bold]]

However, this traces the original function f (x) and f (x) simultaneously; How can I achieve the desired result?
