Which provides evidence that humans are causing an increase in the carbon dioxide concentration in the atmosphere?

A. The net flux of carbon into the atmosphere without including the contribution from burning fossil fuels is positive.

B. The net flux of carbon out of the atmosphere without including the contribution from burning fossil fuels is zero.

C. The net flux of carbon into the atmosphere without including the contribution from burning fossil fuels is negative.

D. The net flux of carbon out of the atmosphere without including the contribution from burning fossil fuels is negative.

The net flux of carbon into the atmosphere without including the contribution from burning fossil fuels is positive.

Explanation:

The human activity of burning fossil fuels inevitably contributes to the increase in carbon dioxide and other gases in the Earth's atmosphere. As a result of this occurrence, a natural greenhouse appears. The greenhouse effect is the process of warming the Earth's surface and the lower layers of the atmosphere, resulting from the leakage of heat radiation.

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 .
