(a) Write an expression involving the values of x and y=f(x)marked on the graph that gives the slope of the line joining theendpoints of the graph.
slope =??
(b) On a print-out of this problem, draw the tangent line to thecurve at the point (x2,y2) . How does the slope of this linecompare with that of your line in (a)?
(c) Give another point on the curve where the slope of the lineis approximately equal to the slope of your tangent line in(b).
