he quadratic regression graphed on the coordinate grid represents the height of a road surface x meters from the center of the road. A graph shows the horizontal axis numbered negative 7 to positive 7 and the vertical axis numbered negative 1.25 to positive 1.25. A line shows an upward then downward trend. What does the graph of the regression model show? The height of the surface decreases from the center out to the sides of the road. The height of the surface increases, then decreases, from the center out to the sides of the road. The height of the surface increases from the center out to the sides of the road. The height of the surface remains the same the entire distance across the road.
