A science class designed a container to protect an egg. Each prototype is launched from a machine at 9.4 meters per second from a roof 40 meters tall. The function f(t) = –4.9t2 + 9.4t + 40 represents the path from the building to the ground on the t-axis, where t is the amount of time since the launch. How do the mathematical range and reasonable range compare? A. mathematical: y ≤ 44.5 reasonable: y ≥ 0 B. mathematical: y ≤ 44.5 reasonable: y ≥ 40 C. mathematical: y ≤ 44.5 reasonable: 0 ≤ y ≤ 44.5 D. mathematical: y ≤ 44.5 reasonable: 40 ≤ y ≤ 44.5
