The value $V(t)$, in dollars, of an investment $t$ years after it was made is modeled by the function $V(t)=5000(1.06{)}^t$. The graph of $y=V(t)$ is shown. If a new investment is made with an initial amount that is 20% less than the original investment, but grows at the same annual rate, which of the following functions would model the value of the new investment?
