step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

the height of the surface increases from the center out to the sides of the road.

is the correct option.
