  1. Linearization is the approximation of the derivative of the function by a tangent line at a particular point.

    at x=1, f'(1)=e
    So the tangent of slope "e" passes through the point (1,e).
    The equation of the tangent line is therefore

    See figure at the link below, and note that the line y=e*x passes through the origin.
