Agas station in a location plans to install an underground gas tank. in your own words, explain how the gas station would affect the humans, economy, and interaction between different earth sphere

If a gas location is tried to set up underground then it is not a good idea as it will affect the animals, plants and human beings near it.

Economically the set up will require huge amount to get set underground as it is a tedious task.

The interaction between the geosphere and hydrosphere will be affected as the underground gas station can leak and reach water which is harmful the people consuming it.

The leakage of gas can also affect the local people of the area residing there. The gas can leak into the atmosphere and can be harmful for the people,animals and plants.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
