The surface of a pedestrian bridge forms a parabola. Let the surface at one side of the bridge be represented by (6,0) and the surface at the other side of the bridge be represented by (14,0). The center of the bridge is 2 feet higher than each side and can be represented by a vertex of (10,2). Write a function in vertex form that models the surface of the bridge.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
