B. chlorofluorocarbons

Answer from: imran2k13

According to the question, Ozone in the upper atmosphere has been depleted by chlorofluorocarbons

Ozone is a form of molecular oxygen and it exists in the upper atmosphere predominantly. It is formed when oxygen is absorbed by the sun-short UVC and then breaking down by some chemicals such as chlorine from chlorofluorocarbons.

Further Explanation

Scientist put together some evidences in the early 1980s to support the fact that ozone layer depletion was as a result of the overabundance of chlorofluorocarbons in the atmosphere.

In industries, chlorofluorocarbons are used as refrigerants, which insulate foam and solvent. However, winds carry chlorofluorocarbons into the stratosphere in a process that could take up to 2-5 years. Chlorofluorocarbons releases chlorine when breaking down into the atmosphere and the chlorine attacks ozone.

The 1920s was a period when refrigerators and air conditioning systems used compounds such as propane, chloromethane, ammonia as refrigerants. Although this compound were very effective but they are very toxic and flammable. Individuals that come in contact with this compound could have a serious injury or death.

However, because of the danger these compound poses, a team of chemists came together to developed nonflammable and nontoxic compounds that are alternative to the refrigerants.

Compound that contains Carbons and halogens such as chlorine and fluorine were the two compounds the team focused on.

Answer from: Quest

we have been given a quadratic function $f(x)=(x-5)^{2} +2$ 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 $[2,\infty)$ .

if we restrict the domain of this function to either $(-\infty,5]$ or $[5,\infty)$ , it will become one to one function.

let us know find its inverse.

$y=(x-5)^{2}+2$

upon interchanging x and y, we get:

$x=(y-5)^{2}+2$

let us now solve this function for y.

$(y-5)^{2}=x-2\\ y-5=\pm \sqrt{x-2}\\ y=5\pm \sqrt{x-2}\\$

hence, the inverse function would be $f^{-1}(x)=5+\sqrt{x-2}$ if we restrict the domain of original function to $[5,\infty)$ and the inverse function would be $f^{-1}(x)=5-\sqrt{x-2}$ if we restrict the domain to $(-\infty,5]$ .
