Consider an initial investment of $100 using an accumulation function which is a second-degree polynomial. You are given that the future values of this investment at the end of six months and the first year are $120 and $150, respectively. Determine the equivalent effective rate of discount between t=0.5, and t=1.5. a) 0.2114 b) 0.2854 c) 0.3684 d) 0.4785 e) 0.5833 Consider an initial investment of $100 using an accumulation function which is a second-degree polynomial.
