. For the net cash flow sequence of -$10,000 in year zero, +$3,000 in year one, -$2,000 in year two, +$8,000 in year three, and +$6,000 in year four, what is the number of possible rate of return values i?

Factor	Name	Formula	Purpose
(F/P, i, N)					Single payment compound amount factor		Moves a single payment to N periods later in time
(P/F, i, N)					Single payment present worth factor		Moves a single payment to N periods earlier in time
(A/F, i, N)					Sinking Fund factor		Takes a single payment and spreads into a uniform series over Nearlier periods. The last payment in the series occurs at the same time as F.
(F/A, i, N)					Uniform Series Compound Amount factor		Takes a uniform series and moves it to a single value at the time of the last payment in the series.
(A/P, i, N)					Capital Recovery Factor		Takes a single payment and spreads it into a uniform series over Nlater periods. The first payment in the series occurs one period later than P.
(P/A, i, N)					Uniform Series Present Worth Factor		Takes a uniform series and moves it to a single payment one period earlier than the first payment of the series.
(P/G, i, N)					Arithmetic Gradient Present Worth Factor		Takes a arithmetic gradient series and moves it to a single payment two periods earlier than the first nonzero payment of the series.
(A/G, i, N)					Arithmetic Gradient to Uniform Series Factor		Takes a arithmetic gradient series and converts it to a uniform series. The two series cover the same interval, but the first payment of the gradient series is 0.
