28

step-by-step explanation:

because that's the answer

b

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one

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.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

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

is the correct option.
