Two students are arguing over the size of the net force acting on a 450kg box when a person pulls it at a constant speed of 7.1m/s across the level ground. James says that the applied force from the person is greater than the friction force but Tony says that the two are equal. Explain who you think is right and use physics equations to support the argument. Thanks in advance!

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 .
