For the function h(x)=x^3-3x+2. Sketch the curve without the use of a graphing calculator. To do so, follow these steps. (a) find the critical points (b) use (a) to find the intervals over which h(x) is increasing and decreasing (c) use (b) to determine any local minimums and maximums (d) find the inflection points (e) use (d) to determine the intervals over which h(x) is concave up and concave down (f) using all of the above, produce a sketch of the graph
