The height in feet of the curved arch support for a bridge over a creek
can be modeled by f(x) = -0.628x2 + 4.5x, where x is the horizontal distance in feet
from where the arch support enters the water. If there is a flood that raises the level
of the creek by 5.5 feet, will the top of the arch support be above the water? Explain.

astronomers is your final answer! : )

i believe the answer is d.

hope it you! : d

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
