Question

Sketch the graph of the polynomial function. Make sure your graph shows all intercepts and exhibits the proper end behavior

P(x)= (x-1)(x+1)(x-2)

Answer 1

help?

Answer 2

I cant use a calculator for this problem

Answer 3

four cheap and easy points can be obtained by setting x=-1, 0, 1, 2

Answer 4

if this is a calc problem, then it would be worth it to FOIL the above binomials. three of the above points are the x intercepts and one point, x=0, is the y intercept.

Answer 5

hope this helps. :)
