Part A The height of a projectile launched from a 16-ft-tall tower is modeled by the equation y = −16t2 + 64t + 16. Which is the correct graph of the equation?
A. A parabola with vertex 2 comma 65 that opens downward and passes through the points zero comma zero and 4 comma zero. B. A parabola with vertex 2 comma 80 that opens downward and passes through the points zero comma 16 and approximately 4 point 2 5 comma zero. C. A parabola with vertex 1.25 comma 36 that opens downward and passes through the points zero comma 16 and 2 point 5 comma zero. D. A parabola with vertex 1 comma 16 that opens downward and passes through the points zero comma zero and 2 comma zero.
