See the graph of gx State the requested values or intervals
     See the graph of g(x). State the requested values or intervals.  State the domain x = (-infinity, infinity)  State the intervals of increase:  State the local minimum value(s).  State the zeros and their possible multiplicity:  Describe the end behavior of the polynomial.  Using the information you found in parts (a) through (e), determine a possible factored form for the polynomial g(x). 
  
  Solution
a) Domain
 ( - inf, inf)
b) Intervals of increas ( -inf , - 2) U ( -1, 1) U ( 2, inf )
c) Local minimum : y = 0 ; y = -1
d) zeros : x= -2 (multiplicty 1)
x= -1 (multiplicty 2)
x = 1.5 (multiplicty 1)
x = 3 (multiplicty 1)
e) x ----> -inf ; y--> - infinity
x ----> + inf ; y-->+ infinity
