For each function and graph in below Problems:

(a) Estimate the coordinates of the relative maxima, relative minima, or horizontal points of

inflection by observing the graph.

(b) Use yf (x) to find the critical values.

(c) Find the critical points.

(d) Do the results in part

(c) Confirm your estimates in part (a)?

1.y = x3 -3x + 4

2.y = x - 1/3 x3

3.y = x3 + 3x2 + 3x - 2

4.y = x3 - 6x2 + 12x +1
