Answer 1

9514 1404 393

Answer:

1. y = 100,000(1 + 0.15)^t
2. y = 1200(1 -0.06)^t
3. y = 49.50(1 -0.07)^t
4. y = 135(1 +0.05)^t
5. value of $200 decreases (decays) by 25% each year

Step-by-step explanation:

It should be no stretch to understand that "increases" means the function is a growth function (+ sign), and "decreases" means the function is a decay function (- sign).

The multiplier in front (a) is the initial value — the value when t=0.
