The 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.

The height of the surface increases, then decreases, from the center out to the sides of the road.

What is quadratic equation?

The polynomial having a degree of 2 is defined as the quadratic equation it means that the variable will have a maximum power of 2.

Let

y------> the height of the surface

x------> the road

we know that

The quadratic regression graphed represent a vertical parabola open downward

The function increase in the interval --------> (-5,0)        

The function decrease in the interval -------->   (0,5)

therefore

The height of the surface increases, then decreases, from the center out to the sides of the road.
