Which of these requires an increase in power? * Doing half as much work in the same amount of time
Doing the same amount of work in half the time
Doing the same amount of work in twice as much time
Doing twice as much work in twice as much time

explanation:

because they are cartillidge

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 .

it would stay the same
