By use of technology, we investigated Mary's investment and created the model, M (x) = 3.03 (1.28) 2x, in thousands of dollars. What was Mary's initial investment?

In this item, we are given with the exponential equation that predicts the amount that Mary is able to obtain through her initial investment. The characters are well identifiable. 3.03 is the initial investment, 28% is the rate and x is the number of years. Thus, the answer is 3.03.
