Question
1.find all the rational zeros of the function. (Enter your answers as a comma-separated list).
2. use the rational zero test to list of possible rational zeros of F. Verify that zeros of f are shown on the graph are contained in the list. enter your answers as a comma-separated list.
3. determine the number of zeros of the polynomial functions.
Explanation / Answer
1.x3-31x -30=0
(x-6)(x+1)(x+5)=0
x=6,x=-5,x=-1
2. g(x)=x3-4x2-4x+4 = x2(x-4)-1(x-1)
= (x2-1)(x-4)=0
(x+1)(x-1)(x-4)=0
x=-1,1,4
