Te arch of the Sydeny Harbor Bridge can be modeled by y= -0.00211x^2 + 1.06x where x is the distance (in meters) from the left pylons and y is the height (in meters) of the arch above the water. For what distances x is the arch above the road? (It has a picture and in it the distance from the bottom of the pylons to the road is 52 m)
