You are given a function that gives you how much the investment is worth after x decades. So if you wanted to know how much the investment is worth after 2 decades, what do you think should be done?

It's rather easy - after 10 years, the amount is 2 * 2,300 = 4,600
So, after 2 decades the amount is 2*4,600 = ???
