Which is a drawback to the use of oil shale to produce energy

Explanation:

Shale oil extraction is a very expensive process. Mining and processing techniques are very costly. Mining of shells of rock have environmental damaging effect. Mining techniques also releases carbon dioxide, so increases global warming. Mining of shale oil also requires large amount of water and it can also contaminate ground water. Waste disposal is also expensive.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
