Whats the meaning of E = mc2?

E =  means Energy is equal to mass of an object multiply by the square of the speed of light

Explanation:

This is gotten from Einstein's law of specific relativity and it is used to determine the energy taking for an object to move from one point to another.

The energy E is measured in Joules (J)

The mass m of the object is measured in Kilogram (kg)

and the speed of light is measured in meter per second (m/s), that is light travels at a specific distance (d) at a given time (t)

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 .
