Exercise 4.2.2 Shown is the graph ofafunction f(x). Sketch the graph off(x) by estimating the deriva- rive ar a number of points in rhe interval: estimate rhe derivative ar regular from one end of rhe interval 10 the other, and also at "special" points, as when lhe derivative is zero. Make sure you indicate any places where the derivative does not exist. Exercise 4.23 Shown is the graph of afunction f Sketch the graph Off' (x) by estimating rhe deriva- tive at a number of points in the interval: estimate the derivative regular intervals from one end of the interval To the other, and also at "special " points, as when rhe derivative is Make sure you indicate any places where the derivative does not exist. 4 3 2 2 3 4 5 Find an the tangent line to the graph Off (x) = 5 x 3x2 at the point x = 2
