Explain the relationship between
the number of ions and the scale.

The pH of a system is dependent on the concentration of hydrogen ions present in that system. The concentration of hydrogen ions in a solution is the amount of hydrogen ions (in the units of mol) present in a liter of solution.

Explanation:

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 .
