When can a truck have less momentum than a bike? A. only when the truck is not moving B. only when it's moving faster than the bike C. only when it's moving more slowly than the bike D. when it's not moving or when it's moving much more slowly than the bike

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

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 .
