Question:

To graph the equation y = –x3 + 3x, we use point-by-point plotting to obtain the graph in Figure 4.

X -1 1 y -2 0 2 Figure 4 -5 5 X

(A) Do you think this is the correct graph of the equation? Why or why not?

(B) Add points on the graph for x = –2, –1.5, –0.5, 0.5, 1.5, and 2.

(C) Now, what do you think the graph looks like? Sketch your version of the graph, adding more points as necessary.

(D) Graph this equation on a graphing calculator and compare it with your graph from part (C).
