The difference between speed and velocity is thata) speed is a vector and requires direction. b) speed is a vector and requires a magnitude. c) velocity is a vector and requires a direction. d) velocity is a vector and requires a magnitude.

Hello,

The answer here would be C

Answer A is wrong, speed does not direction.

Answer B is wrong, Speed is not a vector.

So I would say Answer C is the correct answer.

Hope this helps.

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 .
