We first find the zeros of the function , the zeros of the function are those at which points the graph of the function crosses or touches the x axis
here we can see in the graph that graph crosses the x axis at two points , 1 and 7
So the zeros of the function are
x=1 and x=7
It means the factor are
(x-1) and (x-7)
So the factorization is given by
(x-1)(x-7)
A,C,B
A’s unit rate is 11.0667
C’s unit rate is 12.009
B’s unit rate is 12.5
I think it will be set up as 2000(.051)^3
