1. what is the kinetic energy of a 65 kg rocket traveling at 109 m/s? ( j ) type answer as a whole number (no decimals). type the number only, not the units. use commas: for example, type 100,000, not 100000 2. what is the momentum of the rocket in the previous problem? ( kg · m/s) type answer as a whole number (no decimals, no commas). type the number only, not the units.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

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 .
