Answer:
the m angle ABC is 19x+12
I think it's x2–1=0 because it's the only one that has -1 for origin of the ordinate
The height of the surface increases, then decreases, from the center out to the sides of the road.
<h3>What is quadratic equation?</h3>
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.
