12. Which of the following is true of an electrolyte? A. It is a component of a cell, but not a battery.
B. It is a component of a wet cell but not a dry cell.
C. It is a component of a dry cell but not a wet cell.
D. It is a component of both a wet cell and a dry cell.​

A

Explanation:

It’s a because a electrolyte reproduces

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 .
