A student adds 5 grams of vinegar to 7 grams of baking soda in a sealed bag. Then she watches the bag inflate as a chemical reaction occurs. Which of these amounts is a CORRECT prediction of the mass of the materials in the container after the reaction is
complete?

The mass will stay the same if the bag stays sealed.

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 .
