Answer:


\boxed{1000}

Explanation:

The formula for the amount accrued [ƒ(x)] on an investment earning compound interest is


f(t) = P(1 + r)^(t)

where

P = the amount of money invested (the principal)

r = the interest rate per payment period expressed as a decimal fraction

t = the number of periods

Your formula is


f(x) = 1000(1 + 0.05)^(x)\\\text{By comparison, we see that the term that represents the amount of money}\\\text{originally invested is $\boxed{\textbf{1000}}$}
