It is important to understand the differences between chemical and physical changes. chemical changes result in new substances, but physical changes do not. which process is an example of a physical change?

f) water turns to steam when boiled over a bunsen burner.

g) carbon combines with oxygen to form carbon dioxide gas.

h) water breaks down into hydrogen and oxygen gases.

i) limestone breaks down into lime and carbon dioxide when heated.

the results is a decrease in air temperature with an increase of altitude.

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 .
