Lily wants to track her stores
progress as time goes on. She makes a table of values with one variable being
time in weeks and the other variable being the amount of money the store makes
in thousands of dollars. Find a polynomial function that models Lilys sales.
(A) f(x) = 1/2 n3-2n2+2n-1
(B) f(x) = 1/2 n3-n2-1
(C) f(x) = 1/2 n3-n2+2n-1
(D) f(x) = 1/2 n3-n2+1/3
