Evaluating each function for the given domain.

Question

an investment of 1,500 in a technology stock doubles every 5 years. The function that models the growth of this investment is f(x) = 1,500 x 2x, where x is the number of doubling periods. How much will the investment be worth after 15 years(hint: calculate the number of doubling periods.)

Answer 1

f(x) = 1500(2^x)

x = 3             (15 ÷ 5)

f(3) = 1500(2³)

 

Can you calculate
