Question: Let f (x) = 4/1+ 2x (a) Plot f (x) over [2, 2]. Then zoom in near x = 0 until the graph appears straight,

Let f (x) = 4/1+ 2x
(a) Plot f (x) over [−2, 2]. Then zoom in near x = 0 until the graph appears straight, and estimate the slope f′(0).
(b) Use (a) to find an approximate equation to the tangent line at x = 0. Plot this line and f (x) on the same set of axes.
