What is the fourth dimension?

The 4th direction is taken as time. To understand this imagine every space we placed next to one another being associated with a moment of time, like images are associated with time in a video and series of these images when played make up a video.

In Physics we call these 4dimensions as spacetime. One element(space) of 4th dimension is exactly one moment in the universe, and series of this describe the whole timeline of events taking place from very beginning to the future of the universe.

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 .

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
