This discussion re-visits the concepts of the slope of the tangent line drawn to

This discussion re-visits the concepts of the slope of the tangent line drawn to a curve studied in Module 2.
Review the help on derivatives (Desmos)Links to an external site. [help.desmos.com] and the Derivatives in Action section (last item listed).
Using the examples in the Using Derivatives to Graph a Tangent Line section, in Desmos, plot the tangent line to the curve (b) from Discussion 1 (attached)
By moving the point along the graph from left to right, identify the intervals where the slope of the tangent line is: a) positive and b) negative; and identify the coordinates of all points for which the slope of the tangent line is: c) zero, and d) does not exist.
