Your R&D department is testing the falling pattern for a new shell to be used for artillery. To perform this test your team tosses a test shell off the edge of a cliff towards a river. Molly, a mathematician team member, was observing and obtained a digital picture of this fall. Using her mathematical knowledge, Molly modeled the shell’s fall with the following quadratic functions: h(t)=-16t2+32t+48 h(t)=-16(t+1)(t-3) h(t)=-16(t-1)2+64 Why does Molly have three equations? Could you convince others that all three of these rules are mathematically equivalent? Which of the forms would be most helpful in answering questions D-F? Explain
