Question: Consider the function shown in Figure.
(a) Write an expression involving f for the slope of the line joining A and B.
(b) Draw the tangent line at C. Compare its slope to the slope of the line in part (a).
(c) Are there any other points on the curve at which the slope of the tangent line is the same as the slope of the tangent line at C? If so, mark them on the graph. If not, why not?
