The Bamboozler, a notorious panda thief, is on the run. To evade capture, he travels 30 km east, then 25 km north, and finally 15 km west. What is the magnitude of the
Bamboozler's net displacement?
52 km
29 km
57 km
70 km

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 .
