The quadratic regression graphed on the coordinate grid represents the height of a road surface x meters from the center of the road. 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.

Step-by-step explanation:

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 -------->        

The function decrease in the interval -------->  

therefore

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

linear pair postulates

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
