Answer:
D
Step-by-step explanation: The vertex is where the curve of the parabola occurs. Pay attention to where the curve of the parabola exists, and write down its coordinates. Over here, the curve is on 3 of the x-axis, and the y-value is 0 because the curve is literally on the x-axis. Any point that is on the x-axis will have no y-value. Hence our answer is (3,0).
It’s would be h=6

7:45-5:51 gives you the difference in times remember 60sec per min (1:54)
turn it into only seconds so 60+54=114s and 7x60+45=645s
114/645 gives you the percentage of difference
