110 A y-f(x) y-f(x) (a) 110 C M- P.1.5) EXAMPLE 1 The graph of a function f is given to the left. Use it to sketch the graph of the derivative f'. SOLUTION We can estimate the value of the derivative at any value of x by drawing the tangent at the point (x, f(x)) and estimating its slope. For instance, for x = 5 we draw the tangent at P in the figure and . This allows us to plot the point P'( estimate its slope to be about 3/2, so f'( = are horizontal, so the ) on the graph of f' directly beneath P. Repeating this procedure at several points, we get the lower graph shown in the figure. Notice that the tangents at A, B, and derivative is there and the graph of f' crosses the x-axis at the points A', B', and C', directly beneath A, B, and C. Between A and B the tangents have --Select-- slope, so f '(x) is-Select-- there. But between B and C the tangents have --Select-- slope, so f '(x) is --Select-- there.
