Derivatives from graphs? ?Use the graph of f to sketch a grap ? h of f?.

SOLUTION Consider the following graph of f The objective is to use the graph of f sketch a graph of f STEP 1 The graph consists of line segments which are the tangent lines. Now to find the slope of the tangent line ,select any 2 points on the line. The slope of a line never changes,so we are free to choose any 2 points. Now substitute the points on the equation of slope m = y21 . x21 Thus,since it is a tangent line ,the slope of the line...
