An above-ground swimming pool is leaking. The function h(d) = 48 - 1.5d gives the height of the water in the pool in inches d days after the leak began. Part A: Evaluate h(0). Show your work. What does this value represent in the problem? Part B: Evaluate h(5). Show your work. What does this value represent in the problem? Part C: Write and solve an equation to determine how long it will take the pool to empty if the leak is not repaired. Explain how you set up your equation. Part D: Based on your answers above, should the domain for this function be restricted? If not, explain why not. If so, explain why and give the restricted domain.
