1. 2000 kg truck traveling at 5 m/s.

2. A 250 kg sailboat traveling at 25 m/s.

3. A 1500 kg elephant walking at 2 m/s.

4. A 100 kg man running at 12 m/s.

the bal will not change its velocity.

the answer is b, have negligible mass

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 .
