Emma throws an object upward from a hill that is 64 feet high. the object has an initial velocity of 48 feet per second. the function y = -16x2 + 48x + 64 represents the height of the object, y, in terms of the time elapsed after the object is thrown, x.

The correct options are B and D.

Step-by-step explanation:
