32. in fiji, the firewalkers perform on pumice after going into a cataleptic trance. why is pumice especially suitable?

Pumice is used for cleaning foot. Foot are wet with warm water and then scrub by pumice so that hard and dry skin can be removed. It is quite effective in cleaning skin.

Pumice is also used as light weight material in concrete mix. Due to it porous texture, it is a good light weight material.

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 .
