Step 1

We first find the slope of the tangent for which we need derivative of f(x).  Differentiating f(x) w.r.t. x we get:

Expand
Step 2

Now, slope is the value of f’(x) at the given point x = 1.

Expand
Step 3

Now, to find any one point on the tangent line, we consider the fact that tangent line is drawn at x=1. This point also lies on ...
