6. A ball dropped from the top of tower A can be modeled by the function h(t) = -9.8t2 + 400, where t is the time after it is dropped and h(t)is its height at that time. A ball dropped from the top of tower B can be modeled by the function h(t) = -9.812 + 200. What transformation describes this change? What does this transformation mean? ​

Can someone me and do the problem plz so i can understand it more better
