One person is moving towards east and another is moving along yhe path bisecting north-east with same velociyy. Then, how can you write the velocity of 2nd person with respect to 1st one?

a and b sometimes have a positive value

another example of kinetic energy would be,

kinetic energy   >     moving energy

radiation

explanation:

heat is transmitted by radiation

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 .
